In a braking control device, a controller is configured to determine an inside and an outside of a turn by using the yaw rate, to calculate a deflection index based on a standard turning amount corresponding to a steering angle and an actual turning amount corresponding to a yaw rate, to reduce the braking torque of the rear wheel on the outside of the vehicle turn based on the deflection index when an excessive deceleration slip of the rear wheel on the inside of the vehicle turn is inhibited during an execution of anti-skid control.

A controller and a control method capable of optimizing a braking force generated by a brake system are obtained. During deceleration of a motorcycle, the controller and the control method according to the invention obtain an estimated vehicle body speed Vbe of the motorcycle that is estimated on the basis of speed information of a wheel, obtain a corrected vehicle body speed Vbc that is obtained by correcting an actually-measured vehicle body speed of the motorcycle to a low-speed side, cause the brake system to generate the braking force that corresponds to the estimated vehicle body speed Vbe in a state where the estimated vehicle body speed Vbe is higher than the corrected vehicle body speed Vbc, and cause the brake system to generate the braking force that corresponds to the corrected vehicle body speed Vbc in a state where the estimated vehicle body speed Vbe is lower than the corrected vehicle body speed Vbc.

A wheel chock system. In one aspect of the invention, an actuator is configured to move a pair of wheel chocks to an activated position in which motion of the wheel is prevented. A control unit controls the actuator and, based upon determination that a plurality of predefined conditions are met, the control unit may after having received an operator-initiated activation request, cause the actuator to move the wheel chocks from the inactivated position to the activated position. In another aspect of the invention, the actuator comprises a bi-directional motor and a gear mechanism, for moving the wheel chocks to the activated position. The invention also relates to a vehicle comprising a wheel chock system.

A parking brake apparatus for a vehicle includes a parking brake controller controlling a parking brake system and arranged to obtain one or more input signals indicative of one or more actions from one or more vehicle systems other than the parking braking system. The parking brake controller is also arranged to provide one or more control signals to be applied to components of the parking brake system to apply parking brakes based upon an adaptive time delay to prevent a vehicle rollaway when the one or more input signals are indicative of the one or more actions meeting respective one or more predetermined conditions.

An automatic braking system for a vehicle includes a sensor system configured to detect the previous speed of the vehicle, occupancy of a driver's seat of the vehicle, and an input to at least one of an accelerator pedal of the vehicle and a brake pedal of the vehicle. The automatic braking system also includes a control module communicatively connected to the sensor system and configured to automatically brake the vehicle when the vehicle was previously stopped, the driver's seat is occupied, and there is no input to the accelerator pedal or the brake pedal.

The disclosed vehicle braking device controls a hydraulic brake system (2) and a regeneration brake system (3) mounted on a vehicle (1) in accordance with an acceleration value and a brake value, and includes a first divider (11), a second divider (12), and a controller (13). The first divider (11) divides a driver demand torque set according to the accelerator value into a target coast torque and a remaining torque. The second divider (12) divides a sum of a deceleration torque set according to the brake value and the target coast torque divided by the first divider (11) into a hydraulic-brake demand torque and a regeneration-brake demand torque. The controller (13) controls the hydraulic brake system (2), using the hydraulic-brake demand torque, and controls the regeneration brake system (3), using a total regeneration brake torque calculated from the remaining torque and the regeneration-brake demand torque. This configuration can improve the feeling of operating the brake, resolving the feeling of the shortage of deceleration.

An electric motor-driven brake device for use in a wheeled vehicle is provided with low costs which appropriately enables the wheeled vehicle running and stopping as it usually does, even when a malfunction and/or abnormality are/is caused in the electric motor-driven brake device. Signal lines of stroke sensors each for detecting the quantity of stroke of a brake pedal are connected to controllers in an electric motor-drive unit for controlling a motor which drives an electric motor-driven piston of a brake pad(s) attached thereat.

The present disclosure relates to a method for autonomously controlling a vehicle performed by a vehicle control system, the vehicle control system comprising a zone control system, a collision prediction system and a braking control system, the method comprising the steps of: defining in the zone control system at least a first zone and a second zone relative to a vehicle position, predicting a collision with an obstacle with the prediction system, autonomously braking the vehicle with the braking control system in a first braking mode if the collision is predicted to occur in the first zone and braking the vehicle with the braking control system in a second braking mode if the collision is predicted to occur in the second zone.

A brake pad state estimation device estimates a brake pad state including at least one of a wear volume and a temperature of a brake pad of a vehicle. The brake pad state estimation device performs: a brake pad state calculation process calculating the brake pad state based on sensor detection information during braking; and an information output process storing the brake pad state information in a storage and/or transmitting the brake pad state information to the outside. The brake pad state estimation device variably sets a processing frequency of at least one of the brake pad state calculation process and the information output process. The processing frequency when a vehicle speed is lower is lower than the processing frequency when the vehicle speed is higher, or the processing frequency when a brake pressure is lower is lower than the processing frequency when the brake pressure is higher.

A control device may be configured for responding to failure for ensuring the stability of a vehicle by switching from a two-wheel-drive mode to a four-wheel-drive mode when detecting failure of the brake system in a two-wheel-drive mode.
