摘要: A motor control device includes an acquisition unit and a torque control unit that controls, by selectively using one of a first map and a second map, a motor torque defined in correspondence with a requested torque and an engine rotation speed in each of the first map and the second map. The torque control unit controls the motor torque using the first map when the battery temperature is less than a switch temperature lower than a limit start temperature at which the motor torque is limited, and controls the motor torque using the second map when the battery temperature is greater than or equal to the switch temperature and less than the limit start temperature. The second map includes a larger assist region than the first map. The assist region of the second map defines a smaller maximum torque than the assist region of the first map.

摘要: A driving assistance device includes a guide line detecting unit, a remaining distance acquiring unit, and a braking control unit. The guide line includes a base-point mark which is provided at a position which is separated a first distance from the scheduled stop position. The guide line detecting unit detects the base-point mark at a measurement position of a captured image and sets the detected position of the base-point mark at the measurement position of the captured image as the center of the base-point mark in an extending direction of the guide line when the base-point mark is detected at the measurement position of the captured image. The remaining distance acquiring unit acquires the remaining distance on the basis of the position of the base-point mark set by the guide line detecting unit.

摘要: A platooning system includes a vehicle control system installed in each of vehicles that include a manually-driven head vehicle. The vehicle control system controls a host vehicle such that the host vehicle follows a lead vehicle through wireless communication between the host vehicle and the lead vehicle. The vehicle control system is installed in the host vehicle and the lead vehicle. The vehicle control system includes a sensor that detects a state of the host vehicle, an actuator that adjusts a behavior of the host vehicle, and a controller that controls the host vehicle. The controller of the head vehicle physically notifies a driver of the host vehicle of a state of a subsequent vehicle by operating the actuator of the host vehicle when a state signal including information that indicates the state of the subsequent vehicle is received through the wireless communication.
