Aktywny tempomat

[Gavzgsbs]

Mam BMW seri 1 F40 ma asystenta pasa ruchu oraz wykrywanie zderzenia czołowego ale nie ma aktywnego tempomatu czy da się go dodać ?

A jakie to są te "większe inwestycje" potrzebne, żeby dołożyć aktywny tempomat?

Pewnie w uproszczeniu:

- pewnie zmiana całej wiązki
- wymiana samego tempomatu na kierownicy
- programowanie

oczywiście jeśli kamera, czujniki, etc są zgodne i będą w pełni się ze sobą komunikować (a nie wywalać błędy)

Do tego radar w zderzaku jest inny

Byłem świadom innego modułu radaru w zderzaku i przycisków na kierownicy. Na YT są filmy, że po wymianie tych elementów w F40 ACC działało P&P - więc zakładałem, że wiązka powinna być jedna do wszystkich opcji.

z tą wiązką to bym jakoś próbował zweryfikować - może ASO? 
Bo moje F40 nie ma kierunku w tylnych lampach i już jest niby inna wiązka.

ACC dziala zarowno z radarem dlugodystansowym jak i krotkodystansowym, ponizewaz wtedy opiera sie to na kamerze, tak jak np. w tanszych autach z grupy VW.

Dokladne informacje ponizej.

Vehicle guidance: Active Cruise Control (ACC)

Functional description

Active cruise control regulates the set speed specified by the driver and, if necessary, also the preselected following distance from a vehicle ahead.

If a front radar sensor long range (FRSF) is installed, the data from the front radar sensor long range (FRSF) is fused with the data from the KAFAS camera in the optional equipment system (SAS).

If a front radar sensor (FRS) is installed, the data from the front radar sensor (FRS) is fused with the data from the KAFAS camera in the optional equipment system (SAS).

The KAFAS camera detects vehicles unambiguously if the rear of the vehicle is detected. In addition, the KAFAS control unit is responsible for determining driving lane information, vehicle positions and vehicle movements. The detection of stationary vehicles is also done by the KAFAS camera.

If the active cruise control is activated, the dynamic stability control (DSC) is also activated if it has previously been deactivated by the driver.

The application range of the active cruise control extends right down to stationary. The distance and speed are regulated automatically.

The minimum set speed that can be set is 30 km/h.

The maximum set speed that can be set is 210 km/h in vehicles with the front radar sensor long range (FRSF) and 160 km/h in vehicles with the front radar sensor (FRS).

If the driver leaves the vehicle at a standstill with the system active, the vehicle is kept stationary with the aid of the parking brake.

In situations in which sharper deceleration is required than the system is able to apply, the driver is prompted to assume control of the vehicle themselves with a visual and acoustic signal.

 

Display

The set speed is displayed in the instrument cluster (KOMBI). During active control, it is shown in green. If the active cruise control is in "stand-by-mode", the set speed is shown in grey. The last adjusted set speed is displayed. In addition, the digital value is displayed briefly following activation of the active cruise control or after the set speed is adjusted. The distance set by the driver is also displayed, as well as any vehicle in front from which a safe following distance is maintained.

 

Required vehicle equipment

• Active cruise control with front radar sensor long range (FRSF)

SA5AU - Driving Assistant Professional

or

SA5DF - Active Cruise Control with Stop&Go function

Note: The Active Cruise Control with front radar sensor long range (FRSF) is only offered in the 7 Series and the 8 Series in the SA5DF "Active Cruise Control with Stop&Go function".

 

• Active cruise control with front radar sensor (FRS)

SA5DF - Active Cruise Control with Stop&Go function

Note: The active cruise control with front radar sensor (FRS) is not offered in the BMW 7 Series and the BMW 8 Series in the SA5DF "Active Cruise Control with Stop&Go function".

 

Operation of the function

The active cruise control is activated via the corresponding button on the multifunction steering wheel. The function can be cancelled via the "RES/CNCL" button on the multifunction steering wheel. Pressing the button again resumes the previously selected set speed and distance again. The last adjusted desired distance is saved on the vehicle key when leaving the vehicle.

For safety reasons, the active cruise control can only be deactivated or placed in "stand-by-mode" when the vehicle is at a standstill, provided the brake pedal is operated at the same time.

Whilst driving, the active cruise control is deactivated by operating the brake pedal.

The driver is able to override the active cruise control at any time by depressing the accelerator pedal and thus accelerate more sharply or cancel a deceleration performed by the active cruise control. This does not deactivated the active cruise control.

 

Adjusting the set speed

The driver is able to adjust the set speed in small or large increments. Operation is via the switch block on the multifunction steering wheel. Lightly pressing the rocker button increases or reduces the set speed by 1 km/h. Each time the rocker button is pressed beyond the pressure point, the set speed is increased or reduced by 10 km/h.

If no vehicle ahead is detected, the speed is regulated to and maintained at the specified set speed.

 

Adjusting the desired distance

The driver can select a desired distance from 4 levels using the corresponding buttons on the multifunction steering wheel.

 

Driving off after standstill

Automatic driving off after standstill is implemented depending on the vehicle equipment.

Implementation with SA5AU "Driving Assistant Professional": Automatic driving off after a standstill is performed based on the Attentiveness Assistant. This is detected using the Driver Camera System (DCS). If the attention of the driver is detected, automatic driving off after standstill is performed. If the attention of the driver is not detected, a display in the instrument cluster (KOMBI) will prompt the driver to drive off by operating the vehicle themselves.

Implementation with SA5DF "Active Cruise Control with Stop&Go function": Depending on how long the vehicle has been stationary, driving off after standstill is either automatic or on request of the driver. The vehicle can drive off automatically if it has been at standstill for a maximum of 30 s. If the vehicle has been at standstill for longer than this period of time, a display in the instrument cluster (KOMBI) will prompt the driver to drive off by operating the vehicle himself/herself. The driver can drive off by depressing the accelerator pedal or operating the rocker button on the multifunction steering wheel. The active cruise control then resumes with the preset values.

 

Control units involved in implementing the function

• Optional equipment system (SAS)
• KAFAS camera (KAFAS)
• Body Domain Controller (BDC)
• Front radar sensor long range (FRSF)
• Front radar sensor (FRS)
• Driver Camera System (DCS)
• Head unit (HU)
• Dynamic stability control (DSC)
• Virtual integration platform (VIP)
• Instrument panel (KOMBI)
• Digital Engine Electronics (DME) or Digital Diesel Electronics (DDE)
• Electronic transmission control (EGS)

Note! The specified control units for implementing the function constitute the maximum installation arrangement with which the function is offered. Some control units may not be installed, depending on the equipment.

 

Function requirements

To activate the function, the following conditions must be met:

• Driver's seatbelt is engaged
• Doors closed
• PWF status "Drive" is active

• Parking brake released

   

The function is automatically deactivated in the following situations:

• Operation of the brake pedal by the driver
• Shifting out of drive position "D"
• Deactivation of the dynamic stability control (DSC) and/or activation of the dynamic traction control
• Regulation by the dynamic stability control (DSC)
• Unfastening of the driver's seat belt when the vehicle is stationary
• Opening of the driver's door when the vehicle is stationary
• Following an extended period at a standstill after the vehicle has been braked and brought to a standstill by the active cruise control

• Blindness of the front radar sensor (FRS) or the front radar sensor long range (FRSF)

   

Possible system limits

Delay

The active cruise control will not decelerate in the following situations:

• At the red traffic lights

  Note: The “traffic light detection” function is available in the selected ECE countries from version 07/2020 onwards. This enables braking at red traffic lights.

• When there is crossing traffic

• When there is oncoming traffic

   

Vehicles swinging out

A vehicle in front is only detected if it is fully in the same lane as the driver's vehicle.

If a vehicle in front suddenly swings out of the driver's lane, the active cruise control may not maintain the set distance.

In these cases, the active cruise control prompts the driver to intervene and either brake or swerve.

 

Cornering

If the selected set speed is too high for a bend, the speed is automatically reduced slightly on the bend. Bends are not detected prematurely. On tight bends, there is also the risk of vehicles driving ahead not being detected or being detected with a significant delay.

When approaching a bend, the active cruise control can briefly adjust to vehicles in the adjacent lane on account of the curvature. Potential vehicle deceleration as a result can be compensated for by brief manual acceleration. Once the accelerator pedal is released, the active cruise control remains active and independently adjusts to the selected set speed.

 

Weather conditions

Unfavourable weather conditions or lighting conditions can result in the following limitation:

• Reduced detection of stationary vehicles

   

These limitations can occur during the following weather conditions, for example:

• Thick fog or heavy rain or snow
• Insufficient light

• Strong backlight

   

Engine power

The selected set speed is also maintained on sections of steep downward slopes. On inclines, it is possible to drop below the selected set speed if the required engine output is insufficient.

In the {ECO PRO} driving mode, it is possible that the vehicle speed may exceed or drop below the set speed in some situations, for example on uphill or downhill gradients, in order to maintain a fuel-efficient driving style.

Notes

• When the {ECO PRO} or {SPORT} driving mode is activated on the driving experience control, active cruise control is also adjusted respectively to a fuel-efficient or sporty driving style
