摘要:
In one embodiment, the invention provides a method for controlling a vehicle brake system while the vehicle is in reverse. The method includes prefilling the brake system upon detecting an object in the vehicle's path. If the vehicle continues to move toward the detected object and a first threshold is reached, light braking is applied. If the vehicle continues to move toward the detected object and a second threshold is reached, heavier braking up to full braking is applied to prevent the vehicle from colliding with the object.
摘要:
A vehicle includes a speed detector detecting a vehicle speed, a brake system and a control system implementing a control mode including determining a threshold speed. The control system further derives an initial brake torque demand proportional to an error between the threshold speed and a vehicle speed exceeding the threshold speed and outputs to the brake system a rate-limited brake torque demand by applying a rate-limit operator based on the error to the initial brake torque demand.

A parking assist system for a vehicle is provided that includes a proximity sensor configured to sense a distance to an obstacle, a parking controller configured to output a distance to target signal and a scheduler configured to process the distance to target signal and output a distance error signal to a control module configured to longitudinally control the vehicle. The scheduler is configured to process both a static and a dynamic distance to target signal.

A trailer backup assist system for a vehicle reversing a trailer is provided herein. The system includes a brake system and a steering system of the vehicle. A controller is configured to output a brake torque request to the brake system and a steering command to the steering system, wherein the brake torque request and the steering command are each based at least in part on a trailer mass.

A safety system is provided that will (i) operate automatically, regardless of distraction or error by the driver or the backover victim; (ii) operate unaffected by the blindspots that block the driver's view or background noise that block audible alarms for the driver or the backover victim; (iii) operate through an external activation, intentional or unintentional, by the potential backover victim or passerby; and/or (iv) remove driver discretion by causing the vehicle to stop upon activation of the safety system by the potential backover victim or passerby.
摘要:
The present invention relates to a vehicle control system (1) for controlling a vehicle (3) to facilitate reversing a trailer (5) coupled to the vehicle (3). The vehicle control system includes a processor (33) configured to receive a target trailer destination (DTAR). The current position of the trailer (5) is determined by the processor (33). A target route (R) is then modelled to guide the trailer (5) from its current position to the target trailer destination (DTAR). The processor (33) is configured to output a vehicle control signal to control the vehicle (3) to guide the trailer (5) along the target route (R). The invention also relates to a method of controlling a vehicle (3) to facilitate reversing a trailer (5).
摘要:
A system and method of maneuvering a vehicle-trailer unit in reverse travel uses at least one sensor generating output information representative of the relative position between the vehicle rear and the trailer front. An electronic processing unit compares the measured quantity with a reference value and determines from the comparison whether the trailer deviates from a straight alignment with the vehicle. If the trailer is not aligned with the vehicle, the system can interfere with the vehicle's steering system, the trailer's brake system, or both.The sensor can be a distance sensor or a camera, and the quantity can be a distance or a marker position. As a reference value for comparison, the method can use a stored value or previously or simultaneously measured values. The method can be activated automatically or by a switch operated by the vehicle driver.
