This driving assistance device includes a target acceleration correcting unit configured as follows: if there was input, from a coupling detection unit, of detection results indicating that a trailer has been coupled, the target acceleration correcting unit outputs a target acceleration, output from an ACC unit, as-is to a drive system; and if there was input of detection results indicating that a trailer (2) has not been coupled, the target acceleration correcting unit corrects to a smaller value the target acceleration, output from the ACC unit, and outputs said corrected target acceleration to the drive system.

This disclosure relates to remote control of a brake controller for a towed vehicle. An example communication system includes a controller management application operating on a mobile device and a brake controller that includes a wireless network controller to communicatively couple to the mobile device. The controller management application manages a plurality of profiles. Each profile includes characteristics of a corresponding towed vehicle. The controller management application receives a selection of one of the plurality of profiles, and determines braking characteristics based on the selected one of the plurality of profiles. The brake controller controls a braking signal to brakes of the towed vehicle according to the braking characteristics.

Technologies and techniques for the restrained movement of a vehicle with a drive unit for accelerating the vehicle, and a braking unit for braking the vehicle. A restraining drive torque is generated by the drive unit, and a braking torque is generated by the braking unit to compensate for the restraining drive torque and thereby to generate a restraining torque in the vehicle, and braking the vehicle by reducing the drive torque. A device and a computer program product may be configured to implement the restraining movement processes and a storage may be configured with a processor to execute the computer program product.

A trailer oscillation and stability control device including an accelerometer and an angular rate sensor. An oscillation detection discriminator detects oscillatory lateral trailer motion in response to trailer displacement data derived from inputs from the angular rate sensor and acceleration signals received from the accelerometer, and then generates corresponding oscillatory event data. A brake controller generates a braking control signal in response to oscillatory event data received from the oscillation detection discriminator.

Systems and methods to control a radar system to perform cross-traffic management in a vehicle with a trailer involve determining a location of the trailer behind the vehicle, and adjusting an initial field of view of the radar system to a modified field of view that excludes the location of the trailer. One or more other vehicles are detected with the radar system having the modified field of view. A cross-traffic alert is implemented based on the detecting the one or more other vehicles.

Systems and methods for coordinating and providing braking assistance between towing vehicles and towed vehicles during towing events, such as bidirectional charging towing events, are provided. The towing braking assistance may be provided by the towed vehicle in the form of an assistive braking torque output to assist the towing vehicle with meeting a target deceleration rate during the towing event. The assistive braking torque output may be provided to account for mutual vehicle deceleration events, brake compensation or brake fade events, and stability events of the coupled vehicles during the towing events, for example.

A trailer brake system may include a trailer brake controller comprising a manual braking control, and a trailer light controller; where the trailer brake controller comprises a brake on/off relay, which responds to the manual braking control.
