A drive control system includes an engine, an electric turbocharger, and a controller. The engine includes a cylinder and a piston provided in a slidable manner inside the cylinder and rotates a crankshaft in accordance with sliding of the piston. The electric turbocharger supplies compressed air into the cylinder. The controller controls the engine and the electric turbocharger. The controller includes at least one processor and at least one memory coupled to the processor. The processor transmits a stoppage signal for stopping the engine to the engine, and stops the piston at a position where a crank angle is within a predetermined range from 60° before a top dead center to 30° before the top dead center by causing the electric turbocharger to supply the compressed air into the cylinder in a period from when the stoppage signal is transmitted to when stopping the engine is completed.

Drive control system

A vehicle includes an in-vehicle activity information acquisition unit, a traveling road information acquisition unit, and a traveling route deriving unit. The in-vehicle activity information acquisition unit is configured to acquire in-vehicle activity information indicating content of an activity to be performed by an occupant in the vehicle while the occupant is traveling on the vehicle. The traveling road information acquisition unit is configured to acquire traveling road information indicating a state of a traveling road relating to a magnitude of an acceleration to be applied to the vehicle. The traveling route deriving unit is configured to derive a traveling route of the vehicle, on a basis of the in-vehicle activity information and the traveling road information.

Vehicle

A control device for a vehicle predicts a collision of the vehicle with an object and then actuates a drive assist device. The control device includes a collision predictor, a drive assist controller, an engine controller, a first power supply system, a second power supply system, a switch, and a switch controller. When a possibility that the vehicle will collide with the object exceeds a threshold, the collision predictor outputs a collision alarm signal. When the collision alarm signal is output during driving of the starter motor, the engine controller stops the starter motor to increase an electric potential of the second power supply system, and the switch controller turns on the switch, based on a difference in electric potential between the first and second power supply systems.

Control device for vehicle

A power supply device for a vehicle includes first and second systems, a switch disposed between the systems, and first and second controllers. The first system includes a first power supply and a first electrical apparatus. The second system includes a second power supply and a second electrical apparatus. The first mode controller executes a low power mode where the switch is turned on to supply electric power from one of the first and second power supplies to the first and second electrical apparatuses. The second mode controller executes a high power mode where the switch is turned off to supply electric power from the first and second power supplies to the first and second electrical apparatuses, respectively. When a discharge electric current of the second power supply exceeds a threshold during the low power mode, the second mode controller switches the power supply mode to the high power mode.

Power supply device for vehicle

A power supply device for a vehicle includes first and second power supply systems, a switch, and first, second, and third mode controllers. The first power supply system includes: a first power supply including a first power storage and a first generator, and an electrical apparatus. The second power supply system includes a second power supply. When an SOC of the first power storage exceeds a lower limit, the first mode controller supplies electric power from the first power supply to the electrical apparatus. When the SOC decreases below the lower limit, the second mode controller supplies electric power from the second power supply to the electrical apparatus via the switch. When an abnormality is detected to have occurred in the switch during the second power supply mode, the third mode controller supplies the electric power from the first power supply to the electrical apparatus.
