A system for and a method of controlling driving of a continuously-operable electronic vacuum pump includes determining conditions for allowing and disallowing first and second electronic vacuum pumps to operate for each braking situation according to vehicle state information associated with braking. The first and second electronic vacuum pumps are driven individually or concurrently according to the determined braking situation. Thus, an optimal negative pressure optimal suitable for the vehicle state information is easily supplied to a booster.

A brake control unit includes a processor, a first high side driver and a second high side driver. The processor sends signals to the first high side driver and the second high side driver. The first and second high side drivers process the signals independent of each other. The processor diagnoses faults and locations of faults based on feedback from the high side drivers. The first high side driver controls the braking of a first trailer brake. The second high side driver controls the braking of a second trailer brake.

An emergency braking system of a single-track vehicle configured to intervene in a braking process of the single-track vehicle includes a plurality of sensors that determine various physical variables. From the physical variables an accident risk actual value is determined, compared with an accident risk target value using an emergency braking system control unit, and if the accident risk actual value exceeds the accident risk target value, the single-track vehicle's brake is actuated by the emergency braking system control unit.

A brake control device includes: a decrease determination unit that determines whether a requested braking force for a vehicle is decreasing; and a brake control unit which, on the condition that the decrease determination unit determines that the requested braking force is decreasing during deceleration of the vehicle, executes ratio change decrease control of reducing the braking force of the vehicle according to the decrease of the requested braking force, while making a braking force distribution ratio smaller than a reference braking force distribution ratio. The reference braking force distribution ratio is the braking force distribution ratio at a time point when the requested braking force starts to decrease.

A travel assisting method for a vehicle which is executed by a processor, comprising: generating a vehicle speed command value based on vehicle information of a subject vehicle; calculating the vehicle speed command value at a predetermined time (a look-ahead time) ahead of a current time based on information of a feature existing ahead of the subject vehicle in a travelling direction, as a look-ahead vehicle speed command value; and controlling the subject vehicle based on the look-ahead vehicle speed command value. Further, a lighting state of a traffic light located around the subject vehicle is detected, and the look-ahead time is set based on the lighting state.

A vehicle control system that is mounted in a vehicle includes a camera and an autonomous driving control device. The camera images a situation in front of the vehicle to acquire camera imaging information indicating an imaging result. The autonomous driving control device controls autonomous driving of the vehicle based on the camera imaging information and decides a maximum speed of the vehicle in the middle of the autonomous driving. In more detail, the autonomous driving control device estimates a maximum visible distance of the camera based on the camera imaging information. Then, the autonomous driving control device variably sets the maximum speed according to the maximum visible distance such that the maximum speed in a case where the maximum visible distance is long becomes higher than the maximum speed in a case where the maximum visible distance is short.
