摘要:
When there is an abnormality in communications between a motor ECU and an HVECU in an automobile, the motor ECU controls a motor such that creep torque or a given torque larger than the creep torque is delivered from the motor. Thus, when there is an abnormality in communications between the HVECU and the motor ECU, the automobile is able to run in a limp home mode.

The present invention enables a deceleration to be readily adjustable in the course of braking control with a torque of a motor mounted on a vehicle. In one embodiment, the vehicle has a power system including an engine 10, a motor 20, a torque converter 30, a transmission 100, and an axle 17 that are linked with one another in series. The transmission is a mechanism that changes over a gear ratio under control of a control unit 70 to vary the transmitted torque. The driver manipulates a gearshift lever in the vehicle to specify a desired deceleration by power source braking. The control unit refers to a predetermined map and specifies a combination of motor torque and gear ratio to attain the specified deceleration. In the course of braking control, the deceleration is corrected according to a step-on amount of an accelerator pedal in a range of play of the accelerator pedal. This arrangement facilitates minute adjustment of the deceleration by the power source braking.

A vehicle (100) includes a motor generator (MG) and an inverter (14) driving the motor generator (MG). A power source apparatus for the vehicle includes a battery (B) as an electric storage device, a step-up converter (12) stepping up a voltage of the electric storage device and supplying it to the inverter, and a controller (30) indicating a target step-up voltage in accordance with a target state of operation of the motor generator (MG) to the step-up converter (12). If it is determined that a current operation state signal of the motor generator (MG) is abnormal, the controller (30) increases the target step-up voltage to a maximum value. Preferably, the vehicle (100) further includes a resolver (20) detecting rotation speed of a rotor of motor generator (MG). The controller (30) determines that the operation state signal is abnormal if an output of the resolver (20) does not satisfy a prescribed condition.

In a manual transmission mode, a downshift instruction signal is outputted by a position sensor, and a shift range is lowered by one gear, as a result of an operation of a shift lever by the driver. The driving force of the vehicle is increased through downshifting. The number of times of downshifting within a predefined time is limited to a predefined number of times.
