A hitch assist system is provided herein. An imaging device captures images of a scene rearward of a vehicle. A controller processes captured images and is configured to control a vehicle suspension system to adjust a height of the vehicle and control the deployment of a power tongue jack of a trailer.

A collision prevention device is mounted on a vehicle and prevents collision against an obstacle by controlling a driving system of the vehicle. This collision prevention device includes an obstacle sensor, an obstacle detection area setting unit, a detector and a vehicle controller. The obstacle sensor transmits one of a light wave, a radio wave and an ultrasonic wave to a predetermined obstacle detection area, and receives a reflected wave of one of the light wave, the radio wave and the ultrasonic wave. The obstacle detection area setting unit sets the obstacle detection area of the obstacle sensor. The detector detects the obstacle in the obstacle detection area based on a detection result of the obstacle sensor. The vehicle controller controls the driving system of the vehicle based on a result of the detection of the detector, and according to the obstacle detection area set by the obstacle detection area setting unit.

A backup assist system for a vehicle reversing a trailer includes a brake module and a throttle module. The system further includes a controller having a vehicle speed detector and coupled with the brake module and the throttle module for implementing a backup mode including detecting an adverse operating condition and then adjusting at least one of the brake module and the throttle module and terminating the backup mode upon detecting the adverse operating condition for a time interval.

A vehicle includes a steering system, a vehicle speed detector, a brake system, and a control system. The control system is coupled with steering system for implementing a backup mode for reversing a trailer including controlling the steering system to maintain the trailer along a path. The control system is further coupled with the speed detector and the brake system and selectively outputs a rate-limited brake torque demand to the brake system to maintain a vehicle speed below a threshold speed.

A vehicle stop maintaining system comprises a foot brake mechanism for braking vehicle wheels by applying hydraulic brake pressure to hydraulic brake mechanisms according to a depression of a brake pedal, a brake force control mechanism having a pressurizer that increases hydraulic brake pressure to be applied to the hydraulic brake mechanisms, braking the wheels by controlling the pressurizer independently from the depression of the brake pedal, and a controller for executing, when the vehicle is detected to be in a stopped state, a first stop mode in which the brake force control mechanism is operated to maintain the stopped state. The system includes a gear position detector for detecting a position of a gear shift lever of the vehicle. When a vehicle driver intentionally controls the gear shift lever to a reverse position in the first stop mode, the controller cancels the first stop mode.

A parking assist system for a vehicle is provided that includes a speed limiting controller configured to set a speed limit for the vehicle during a maneuver and an audio sensor configured to sense an ambient sound within the vehicle. The speed limiting controller is configured to reduce the speed limit based on the sensing of the ambient sound within the vehicle.

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 backup assist system for a vehicle reversing a trailer includes a brake module and a throttle module. The system further includes a controller having a vehicle speed detector and coupled with the brake module and the throttle module for implementing a backup mode including detecting an adverse operating condition and then adjusting at least one of the brake module and the throttle module and terminating the backup mode upon detecting the adverse operating condition for a time interval.

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.
