An electric vehicle steering system including a vehicle controller, steering controller, braking controller, and a steering actuator. The vehicle controller, in cooperation with the steering and braking controllers, is responsible for collecting and processing various vehicle conditions to determine a braking application. The steering controller, linked to steering actuators, executes braking application instructions from the vehicle controller. The braking controller, connected to the vehicle's braking system, executes instructions to apply brakes as needed.

Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination. Using a driver deceleration demand a pressure level and/or duration for a preliminary pressure peak to be provided in one or more fluid lines of the trailer brake system is determined. A trailer brake signal is generated for controlling the trailer brake system in accordance with the preliminary pressure peak.

Disclosed is a number of variations that may include a method, system, or computer product useful in determining an intended yaw or yaw rate that a driver desires using a model, comparing the yaw or yaw rate with the actual vehicle yaw or yaw rate to determining a yaw error or yaw rate error, using the yaw error or yaw rate error in a model predictive control to determine the brake pressure required to minimize or reduced to zero the yaw error or the yaw rate error.

Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination. A HMI component used by the operator to provide a deceleration input to the trailer brake system is identified. Based on this a pressure level to be provided in one or more fluid lines of the trailer brake system is determined. A trailer brake signal for is generated and output controlling the trailer brake system to provide the determined pressure.

Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle, comprising: determining a coupling force associated with a coupling point for providing a coupling between the vehicle and a trailer, determining, in dependence on the coupling force, the presence of a trailer coupled to the vehicle at the coupling point; and controlling one or more components of the vehicle in dependence on the determination of the presence of the trailer.

A driving dynamics system for a vehicle may include a primary control unit for detecting and/or generating steering commands and braking commands; a brake system having first and second electrohydraulic pressure supply units; four hydraulically actuable wheel brakes of respective wheels; electrically actuable brake pressure adjustment valves; and an electric steering actuator for actuating at least one axle. The driving dynamics system may implement a steering command during normal operation to actuate at least one of the pressure supply units and the steering actuator and/or, to implement a braking command during normal operation, to actuate at least the second pressure supply unit and at least the brake pressure adjustment valves for a wheel-specific pressure adjustment and, in a fault case, to actuate at least the first pressure supply unit and at least the brake pressure adjustment valves for a wheel-specific pressure adjustment.

It is an object of the present invention to provide an electric brake device capable of accurate control at low cost. The present invention includes a motor control device 11 that controls rotation of an electric motor 8 for pressing brake pads 5a, 5b. The motor control device 11 is provided with: a motor position-current relationship generation portion 43 that acquires a relationship between the rotational position and the current of the electric motor 8; a braking torque estimation portion 41 that estimates braking torque pressing the brake pads 5a, 5b, on the rotational position of the electric motor 8; and a braking torque-position relationship portion generation portion 42 that acquires a relationship between the rotational position and the braking torque of the electric motor 8 on the basis of information from the motor position-current relationship generation portion 43 and the braking torque estimation portion 41. The rotation of the electric motor 8 is controlled on the basis of information from the braking torque-position relationship portion generation portion 42.

An automatic emergency braking device, which is configured to prevent delay and malfunction of an automatic emergency brake when a vehicle enters an opposite lane, includes a collision determination unit that executes a collision determination for determining a possibility of collision between the vehicle and an oncoming vehicle. The automatic emergency braking device further includes a brake control unit that activates the automatic emergency brake according to the determination result of the collision determination, and an execution timing change unit that changes the execution timing of the collision determination. The execution timing change unit includes a determination unit that determines whether a prediction condition indicating prediction of entry of the vehicle to the opposite lane is satisfied, and a setting unit that, when the condition is satisfied, sets the execution timing of the collision determination earlier than the timing in the case where the condition is not satisfied.

An electronic mechanical braking method for an intelligent vehicle, a new energy vehicle, or a traditional automobile includes obtaining status information of a first control unit for performing braking control on a vehicle, where the status information is indicates whether the first control unit works normally, and when the status information indicates that the first control unit cannot work normally, performing the braking control on the vehicle using a second control unit.
