Abstract: A vehicle control apparatus is provided that can maintain an automatic engine stop function when an abnormality occurs in a preceding vehicle following control function. The vehicle control apparatus includes a first control unit configured to include a preceding vehicle following control function to control vehicle speed, based on a traveling state of a preceding vehicle, and to output a prohibition request to an automatic engine stop function; and a second control unit configured to include the automatic engine stop function, and to maintain the automatic engine stop function, contrary to the prohibition request output from the first control unit, when an abnormality occurs in the preceding vehicle following control function.

Abstract: A controller for a vehicle executes, when an ignition switch is turned off before an engine speed increases to an autonomous speed that is a speed allowing for autonomous operation of an engine, an increase process that increases the engine speed to greater than or equal to the autonomous speed, and a stop position control that stops a piston at a predetermined position in a cylinder through regenerative braking that converts rotational energy of a crankshaft of the engine into electric power with a motor generator after the increase process is completed.

Abstract: A control apparatus for a vehicle allows execution of an idle-stop control for temporarily stopping an engine, in a case in which a plurality of conditions are satisfied. The plurality of conditions include (i) a first condition is that it is determined upon power ON of the vehicle that the execution of the idle-stop control is allowed in a result of a determination stored upon power OFF of the vehicle last time and (ii) a second condition that it is determined that a smoothed value of an output voltage of a power storage device is at least a predetermined voltage value that guarantees the start of the engine. The smoothed value is obtained by a smoothing processing for smoothing the output voltage during a preparation period from the power ON until elapse of a predetermined time for which an initialization processing of the control apparatus is executed.

Abstract: A hydraulic control device that includes a source pressure generating valve that generates a source pressure; a solenoid valve that can supply the engagement pressure based on the source pressure; and a supply pressure switching valve that can be switched between a first state where the supply pressure switching valve can supply the engagement pressure to the second engagement element and a second state where the supply pressure switching valve can supply the source pressure to the second engagement element, the supply pressure switching valve being in the first state when the solenoid valve is operating normally, and being switched to the second state in case of abnormality in the solenoid valve.

Abstract: A control apparatus for a vehicle that is provided with (i) an engine, (ii) a first starting device including an electric motor and a high-voltage power supply device, such that the first starting device cranks the engine by using the electric motor, (iii) a second starting device including a starter motor and a low-voltage power supply device, such that the second starting device cranks the engine by using the starter motor, and (iv) various kinds of electrical equipment operable by an electric power supplied from the low-voltage power supply device. In a case in which start of the engine by cranking the engine by using the first starting device has failed and then the start of the engine by cranking the engine by using the second starting device has failed, the control apparatus cranks the engine by using the second starting device again.
