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.

Control apparatus for vehicle

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.

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.

Hydraulic control device for automatic transmission

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.

Vehicle control apparatus

An engine control device applied to a vehicle equipped with an actuator for changing a suspension property of the vehicle, a suspension control device for driving the actuator, and an engine. The engine control device automatically stops the engine operation when a stop condition is satisfied and automatically starts the engine operation when a start condition is satisfied, continues the engine operation when a signal for inhibiting the automatic stop of the engine operation is sent to the engine control device in order to drive the actuator and the engine control device judges that no malfunction occurs in the suspension control device even if the stop condition is satisfied, and ignores the signal and automatically stops the engine operation when the stop condition is satisfied and judges that the malfunction occurs in the suspension control device even if the signal is sent to the engine control device.

Engine control device

The engine control device is applied to a vehicle equipped with a suspension control device for driving stepping motors for changing damping forces of shock absorbers. The suspension control device performs an initializing process for resolving the step-out of the stepping motors by driving the stepping motors when an initialization performing condition is satisfied. The engine control device continues the engine operation when a signal for inhibiting the automatic stop of the operation of the engine is sent to the engine control device and the engine control device judges that no malfunction occurs in the suspension control device even if the engine stop condition is satisfied. The engine control device automatically stops the operation of the engine when the engine stop condition is satisfied and the engine control device judges that a malfunction occurs in the suspension control device even if the signal is sent to the engine control device.

A switch of a connecting circuit is connected between a signal line branched from an input terminal for a pilot signal in a charging inlet and a ground line connected to a vehicle earth, and is turned on/off in response to a control signal from a CPU. The CPU causes the switch to be turned on when a connector is not connected to the charging inlet, and detects a break in a control pilot line based on whether or not a change in the potential of the pilot signal occurs at that time.

Charging control apparatus for vehicle and vehicle

An oscillator provided in a charging cable outputs a non-oscillating signal when the potential of a pilot signal is around V(), and outputs an oscillating signal when the potential of the pilot signal is lowered to V(). A pull-down resistance element provided in the plug-in hybrid vehicle is connected between a control pilot line and a vehicle earth, and changes the potential of the pilot signal from V() to V(). A switch is connected in series between the pull-down resistance element and the vehicle earth. When the charging cable is connected to the vehicle, the switch is turned off and the pull-down resistance element is separated from the vehicle earth.

Charging control apparatus for vehicle

Provided is a charging cable capable of detecting an abnormal state, such as a break, of a control line through which a pilot signal is transmitted, the charging cable including: a power cable through which an external power source feeds a power storage device; a signal generating circuit for generating a control signal to output to a vehicle; a control line Lthrough which the control signal is transmitted to the vehicle; and a bypass circuit for changing a voltage applied from a vehicle side through the control line L
