Vehicle control apparatus
The control apparatus according to the invention is applied to a hybrid vehicle having a manual transmission. The control apparatus controls a motor-generator such that a torque is input to the manual transmission when a neutral switch outputs a detection signal while an internal-combustion engine and the vehicle are stopped. The control apparatus starts up the internal-combustion engine when a release manipulation is performed to a clutch while the time rate of change of input-side rotating speed of the manual transmission by a torque providing control does not satisfy a predetermined criterion.
1. A vehicle control apparatus applied to a vehicle including: an internal-combustion engine and an electric motor provided as running power sources; a manual transmission to which a torque of each of the internal-combustion engine and the electric motor is inputted, and to which a driver is allowed to perform a start shift manipulation in order to switch from a neutral position to a predetermined start shift position; and a clutch to which the driver is allowed to perform a release manipulation in order to interrupt a torque transmission between the internal-combustion engine and the manual transmission,
the vehicle control apparatus including at least one Electronic Control Unit (ECU) and comprising:
a start-up controlling device, which the ECU is programmed to function as, configured to start up the internal-combustion engine under at least one condition that, in a state that the internal-combustion engine is stopped and also the vehicle is stopped, the release manipulation is performed to the clutch and also the start shift manipulation is performed to the manual transmission;
a neutral-position detecting device configured to output a detection signal when the manual transmission is at the neutral position; and
a torque providing controlling device, which the ECU is programmed to function as, configured to execute a torque providing control to control the electric motor such that the torque is inputted to the manual transmission when the neutral-position detecting device outputs the detection signal in the state that the internal-combustion engine is stopped and also the vehicle is stopped,
wherein the start-up controlling device is configured to start up the internal-combustion engine when the release manipulation is performed to the clutch in a case that a change of input-side rotating speed of the manual transmission caused by the torque providing control does not satisfy a predetermined criterion.
2. The vehicle control apparatus according to claim 1 , further comprising
a breakdown diagnosing device, which the ECU is programmed to function as, configured to diagnose a breakdown of the neutral-position detecting device based on the change of the input-side rotating speed of the manual transmission caused by the torque providing control,
wherein the start-up controlling device is configured to start up the internal-combustion engine in a case the release manipulation is performed to the clutch in a state that a condition of the neutral-position detecting device is diagnosed as a breakdown by the breakdown diagnosing device.
3. The vehicle control apparatus according to claim 2 , wherein
the breakdown diagnosing device is configured to diagnose the condition of the neutral-position detecting device as the breakdown when the change of input-side rotating speed of the manual transmission by the torque providing control does not satisfy the predetermined reference.
4. The vehicle control apparatus according to claim 1 , wherein
the vehicle includes a brake device having a brake pedal to be manipulated by the driver, the brake device being configured to based on the manipulation to the brake pedal, switch a state between a braking state in which the vehicle is braked and a release state in which the braking state is released, and
the torque providing controlling device is configured to start the torque providing control, when the brake pedal is switched from a manipulation state to a non-manipulation state with this as a trigger.
5. The vehicle control apparatus according to claim 4 , wherein
the vehicle is provided with a braking-state retention device, which the ECU is programmed to function as, configured to keep the brake device in the braking state in a case that the brake pedal is switched from the manipulation state to the non-manipulation state, and
the torque providing controlling device is configured to control the braking-state retention device such that the torque providing control is executed in a state that the brake device is kept in the braking state.
6. The vehicle control apparatus according to claim 1 , wherein
the torque provided by the torque providing controlling device is set as a microtorque having a level of magnitude with which the vehicle is not driven but the manual transmission idles in the state of the neutral position.
