Abstract: To a first electronic control unit, three or more sensors excluding one predetermined sensor are connected. To a second electronic control unit, two sensors, which include one common sensor, of the three or more sensors, are connected. When the first electronic control unit does not determine that a sensor in a normal state is present among the three or more sensors, and the second electronic control unit determines that both of the two sensors are in the normal state, the electronic control unit controls the brake circuit based on the operation amount detected by at least one of the predetermined sensor or the common sensor.

Abstract: A vehicle includes vehicle devices configured to adjust a lateral movement amount of the vehicle, and a steering wheel lock mechanism. The vehicle devices include a front-wheel steering device and a remaining device that is a device other than the front-wheel steering device. When there is an anomaly in the front-wheel steering device, a vehicle control device switches a state of the steering wheel lock mechanism from a deactivated state to an activated state. The control device adjusts the amount of lateral movement of the vehicle by activating the remaining device when rotation of the steering wheel is disabled.

Abstract: A control device for a vehicle includes one or more processors configured to: perform feedback control on an acceleration of the vehicle by controlling a driving force of an internal combustion engine mounted on the vehicle based on a difference between a requested acceleration of the vehicle from an application and an actual acceleration of the vehicle; calculate a first predicted acceleration that is a predicted acceleration of the vehicle on an assumption that the internal combustion engine is controlled into a fuel-cut state; and control the internal combustion engine into the fuel-cut state without performing the feedback control when a coasting condition that is predetermined is satisfied and the first predicted acceleration is equal to or higher than a lower limit value that is predetermined as a negative value.

Abstract: A brake device includes: a first pressurizing unit configured to increase a WC pressure by supplying brake fluid into wheel cylinders provided in wheels RL and RR; a second pressurizing unit connected to a reservoir tank via a fourth flow passage and configured to increase the WC pressure by supplying the brake fluid taken in from the reservoir tank into the wheel cylinders; and a brake control unit configured to control at least one of the first pressurizing unit and the second pressurizing unit based on a target WC pressure. The brake control unit is configured to, when the WC pressure is to be increased by operating the second pressurizing unit, execute an auxiliary brake control in which the first pressurizing unit is operated to assist the second pressurizing unit to increase the WC pressure.
