A control arrangement and a method for deactivating an adaptive cruise control system. The method comprises, in response to a determination of risk of loss of functionality of the adaptive cruise control system while the host vehicle is decelerated by the adaptive cruise control system, determining whether the host vehicle may be braked by the service brake system; and, if so, activating a first failure mode during which the adaptive cruise control system is maintained active to decelerate the host vehicle until a deceleration demand is below a predetermined threshold. The method further comprises, when the deceleration demand is below the predetermined threshold, either ramping down the braking demanded by the adaptive cruise control system over a predetermined period of time and thereafter deactivating the adaptive cruise control system, or directly deactivating the adaptive cruise control system.

A vehicle auxiliary braking system, comprising a carbon brake arrangement, the carbon brake arrangement comprising a rotatable carbon brake disc operably connectable to at least one wheel of a vehicle, and brake pads operable to engage with the rotatable carbon brake disc, the vehicle auxiliary braking system further comprising a control unit comprising processing circuitry configured to determine a time period for an upcoming vehicle braking operation to be initiated at a brake start position at future point in time, and control the brake pads to engage with the rotatable carbon brake disc at the brake start position in response to the time period exceeding a predetermined threshold time period.

A vehicle braking control apparatus includes a controller and a determiner. The controller is configured to switch between a braking-force generating control and a braking-force release control. The controller causes a braking device mounted on a vehicle to generate a braking force in the braking-force generating control and causes the braking device to release the generated braking force in the braking-force release control. The determiner is configured to determine whether an unstable-behavior with rotation around a rotation axis along a vertical direction occurs or not in the vehicle based on a determination-value determined by a state occurred in the vehicle and a state of a road surface with which wheels of the vehicle are in contact. The controller causes the braking device to generate the braking force by executing the braking-force generating control when the determiner determines that the unstable-behavior occurs.

A vehicle braking device with electric brakes includes a braking force controller. This controller adjusts braking forces based on an external command. The electric brakes show hysteresis characteristics: braking force rises with increasing current along a positive efficiency line and holds steady when current drops from a turning value to a holding threshold. Further current decrease leads to a reduction in braking force along an inverse efficiency line. The actual braking force has an increasing period when it follows the positive efficiency line and a holding period when it stays constant as current decreases to the holding threshold. If the vehicle does not meet an exclusion requirement and the required braking force is rising, the controller switches from the increasing period to the holding period when the actual braking force matches the target braking force. It switches back to the increasing period when the difference between the actual and target braking forces reaches a predetermined threshold.

The brake device may comprise: a hydraulic pressure supply unit fluidically connected to wheel cylinders of a vehicle; a parking brake arranged at at least one of the wheel cylinders; a first processor electrically connected to the hydraulic pressure supply unit and the parking brake; and a second processor electrically connected to the parking brake, and electrically connected to the first processor through a signal line. The first processor can control the hydraulic pressure supply unit on the basis of output signals of a pedal sensor of the vehicle, control the parking brake on the basis of output signals of a parking switch of the vehicle, and provide periodic signals to the second processor through the signal line. The second processor can control the parking brake on the basis of the output signals of the pedal sensor if the periodic signals of the first processor are not received.

A method for controlling vehicle braking of a wheel rotor having a brake pad associated therewith includes moving a piston into engagement with the brake pad by applying hydraulic pressure to the piston. The piston is locked in place against the brake pad with a parking brake. The hydraulic pressure is removed from the piston while the parking brake is locked.

The autonomous emergency braking apparatus comprises a vehicle controller arranged to (i) monitor the one or more sensor signals indicative of the status of the at least one vehicle adjacent to the host vehicle, and (ii) provide at least one control signal for controlling extent of deceleration of the host vehicle based upon the status of the at least one vehicle adjacent to the host vehicle in the event of the host vehicle colliding with a vehicle in front of the host vehicle.

A child protection zone driving assistance device includes a transceiver configured to receive image data received from a surveillance camera having a constant sensing field of view within a child protection zone from a communication device and a processor configured to recognize a pedestrian based on the image data, determine location information about the pedestrian as either left or right based on a driving direction when the pedestrian is recognized, and control a display device of a vehicle to display the determined location information, and may display a location of the pedestrian present in a blind spot in the child protection zone as left or right based on the driving direction of the vehicle together with a warning, thereby encouraging safe driving and improving driving convenience.
