A method is provided for decelerating a vehicle. The vehicle has an electro-pneumatic brake system, at least one front axle, at least one rear axle, and a brake value transmitter. The vehicle further includes at least one axle modulator for the front axle of the vehicle, for performing control of at least one front axle brake pressure at the at least one front axle, and/or at least one axle modulator for the rear axle of the vehicle, for performing control of a rear axle brake pressure at the at least one rear axle of the vehicle. The method includes generating a redundancy signal at a first axle, the front axle or rear axle, or at a trailer control valve, and performing open-loop and/or closed-loop control of an auxiliary brake pressure at another axle, the front axle or the rear axle, via the redundancy signal.

A controller for a vehicle is provided. One of a prime mover that drives a front wheel and a prime mover that drives a rear wheel is referred to as a first prime mover, and the other one is referred to as a second prime mover. The controller generates, when a required torque required for a drive wheel of the vehicle is a braking torque, the braking torque from the first prime mover. The controller limits, when the required torque changes from the braking torque to a driving torque, an increase in the driving torque generated from the first prime mover during a set period. The controller generates, from the second prime mover that does not generate the braking torque, the driving torque required during execution of the torque limit process.

A brake system for a motor vehicle, having a first hydraulic brake device configured to brake wheels on a first axle of the motor vehicle, a first control unit configured to control the braking operation of the wheels on the first axle; and a second hydraulic brake device configured to brake the wheels on a second axle of the motor vehicle, and a second control unit configured to control the braking operation of the wheels on the second axle. The first control unit is coupled with the second control unit via a communication channel. The first control unit and the second control unit are each configured to receive data that are relevant for the control of the braking operation, the first control unit furthermore being configured to transmit a data signal on the basis of the received data via the communication channel to the second control unit.

A method of braking a host vehicle traveling behind a second vehicle includes acquiring visual images of the second vehicle and determining an actual deceleration of the second vehicle based on the visual images. Non-visible light emitted by the second vehicle is detected. A commanded deceleration of the second vehicle is determined based on the detected light. A first signal is produced indicative of the actual deceleration. A second signal is produced indicative of the commanded deceleration. Braking of the host vehicle is initiated in response to at least one of the first and second signals.

A method for controlling a vehicle brake system of a heavy duty vehicle, the brake system comprising a service brake system and an electrical machine brake system. The method includes determining a total brake torque request for braking a wheel of the vehicle, obtaining a brake torque capability of the electrical machine, determining if the total brake torque request exceeds the brake torque capability of the electrical machine, and if the total brake torque request exceeds the brake torque capability of the electrical machine but is below a threshold level, applying a baseline brake torque by the service brake system, wherein the baseline brake torque is configured to compensate for a difference between total brake torque request and brake torque capability of the electrical machine, and controlling wheel slip by the electrical machine brake system.

A brake system for a motor vehicle, particularly a commercial vehicle, includes at least one electronic control unit, at least one parking brake device, and at least one wheel-blocking detection device. The wheel-blocking detection device is configured to: detect at least one blocking condition of one or more wheels of the motor vehicle, generate at least one blocking condition signal in response to the detected blocking condition, and transmit the blocking condition signal to the electronic control unit. The electronic control unit is configured to control the parking brake device such that, in a moving condition of the motor vehicle, at least one gradual actuation of the parking brake device is reduced or stopped if the blocking condition signal is generated.

The present invention obtains a controller and a control method capable of hastening identification of an object or an event to be focused by a rider of a straddle-type vehicle, the rider having perceived haptic motion.

A controller (51) for a rider-assistance system (50) mounted to a straddle-type vehicle (100) includes: a determination section that determines necessity of a warning given to the rider; and a haptic motion performing section that performs haptic motion at least once to reduce or increase acceleration/deceleration of the straddle-type vehicle (100) only for a moment. The haptic motion performing section changes a priority of each wheel (3, 4) at the time of changing a braking force to reduce or increase the acceleration/deceleration only for the moment in the haptic motion according to a focusing direction that is a direction in which the rider should focus by the warning.

A hydraulic pressure control unit capable of suppressing application of an external force thereto in comparison with the related art at the time when mounted to a straddle-type vehicle is obtained.

A hydraulic pressure control unit (1) includes: a base body (10) formed with an internal channel through which a brake fluid flows; an inlet valve and an outlet valve that open/close the internal channel during anti-lock brake control; a first coil (61) as a drive source of the inlet valve; a second coil as a drive source of the outlet valve; and a circuit board (36) that is electrically connected to the first coil (61) and a second coil and controls energization of the first coil (61) and the second coil. The base body (10) is held to a front fork (216). When the straddle-type vehicle to which the hydraulic pressure control unit (1) is mounted is seen in a front view, the circuit board (36) is located behind the front fork (216) and the base body (10), and the first coil (61) and the second coil are erected from a rear surface of the base body (10).

The present disclosure relates to an electrified vehicle capable of handling a situation where there may be an insufficient brake force during long-time braking by applying regenerative braking and to a braking compensation control method of the electric vehicle. The braking compensation control method includes determining whether a preset compensation control entry condition may be satisfied, determining a compensation brake torque for assisting in following a speed of a leading vehicle traveling ahead, and outputting the compensation brake torque through a motor when the compensation control entry condition may be satisfied.
