A method and device for improving trailer brake response during a hard braking event by identifying unnecessary attenuation of a trailer braking signal, and responding by boosting the trailer braking signal.

A method for operating a motor vehicle, which includes a drive system, including an electric drive machine, a friction braking system and an actuating element. The actuating element is continuously movable between a first end state and a second end state, a position of the actuating element in the first end state corresponding to a percentage value of 0%, and the position of the actuating element in the second end state corresponding to a percentage value of 100%. An acceleration torque for the motor vehicle is predefined if the positon has a percentage value that is greater than a predefined threshold value, and a deceleration torque for the motor vehicle being predefined if the position has a percentage value that is less than the threshold value. The friction braking system is activated in such a way that the friction braking system generates at least partially the predefined deceleration torque.

A method of controlling an idle speed of an engine of a vehicle, includes the steps of determining that the engine is decelerating to or is operating at a nominal idle speed, determining that a vehicle brake is applied, determining an actual or projected electrical load of at least part of a vehicle electrical system is beyond an electrical load threshold, and increasing the engine speed to or maintaining the speed of the engine at a speed greater than the nominal idle speed range as a function of the electrical load to increase the electrical output of a generator coupled to the engine. The method may include determining that the brake is ceasing to be applied and then decreasing the engine speed to or toward the nominal idle speed.

This application provides a torque compensation method for a vehicle, a torque compensation apparatus of a vehicle, and an associated computer-readable storage medium. The torque compensation method includes: when a vehicle control module determines that the vehicle is in a sliding state during a brake idle stroke, obtaining, by the vehicle control module, a pressure of a brake master cylinder of the vehicle, and controlling a motor of the vehicle based on the pressure of the brake master cylinder to output a compensation torque. In this application, a range of the brake idle stroke of the vehicle can be precisely determined, so as to control the motor of the vehicle to output the compensation torque in a timely manner, thereby effectively suppressing sliding during the brake idle stroke of the vehicle and ensuring safe driving.

The present disclosure relates to an electronic brake system and an operation method thereof. The electronic brake system includes a reservoir in which a fluid is stored, a hydraulic pressure supply device configured to generate a hydraulic pressure by operating a hydraulic piston in response to a signal from a pedal displacement sensor detecting a displacement of a brake pedal, a hydraulic control unit including a first hydraulic unit configured to control the hydraulic pressure to be transferred from the hydraulic pressure supply device to a first hydraulic circuit including two wheel cylinders, and a second hydraulic unit configured to control the hydraulic pressure to be transferred from the hydraulic pressure supply device to a second hydraulic circuit including other two wheel cylinders.

In an electronic parking braking system and a control method thereof, the system includes a transmission apparatus, a main parking braking controller and an auxiliary parking braking controller. The transmission apparatus sends a parking request signal when a parking (P) stage is input. The main parking braking controller determines whether being capable of performing a main parking braking control upon receiving the parking request signal, performs the main parking braking control upon determining that the main parking braking controller can perform the main parking braking control, and sends a failure signal to the transmission apparatus upon determining that the main parking braking controller cannot perform the main parking braking control. When the transmission apparatus receives the failure signal, the auxiliary parking braking controller may perform an auxiliary parking braking control. The auxiliary parking braking controller performs an auxiliary parking braking control based on the parking request signal in an activation state.

A method for operating a braking system for a motor vehicle, which has a service brake device with at least one wheel brake and a brake pressure applied to the wheel brake for generating a braking force acting on a brake disc of the wheel brake is adjusted at least temporarily depending on a setting of an operating element. A condition of a coating of a brake disc of the wheel brake is determined based on the brake pressure applied to the wheel brake and a deceleration of the motor vehicle resulting therefrom.

A control pedal device includes: a pedal configured to receive an operation; a pedal arm attached to the pedal to be movable with the pedal; a rotating shaft fixed to the pedal arm; a reaction force generating mechanism exerting a reaction force against the operation of the pedal; multiple targets attached to the rotating shaft and rotating together with the rotating shaft; and multiple sensor elements configured to detect a rotation of the multiple targets.

A brake apparatus for a wheel of a vehicle, comprising a brake pad to generate a brake force when the brake pad engages a brake disc, the brake disc being associated with the wheel of the vehicle a brake actuator, which is adapted to move the brake pad towards the brake disc, and bring the brake pad into contact with the brake disc, therewith generating a requested brake force in response to a brake action request, a control unit configured to determine whether a brake action request is present, determine whether the vehicle is standing still, instruct the brake actuator to reduce the brake force with which the brake pad engages the brake disc when the control unit has determined that the brake action request is present and the control unit has determined that the vehicle is standing still.

The present invention relates to an electronic control unit (ECU) structure of a brake system. An ECU of a brake system, according to the present invention, has a redundancy configuration in which a first control unit, a first cover, and a second control unit are sequentially stacked so that the first control unit and the second control unit are spatially separated by means of the first cover, and thus the second control unit can perform the function of the first control unit without being influenced when the first control unit malfunctions.
