- the electric power generated by the first motor generator 110 is selectively used according to the running state of the vehicle and the state of SOC (State Of Charge) of the battery 150. For example, during normal traveling, the electric power generated by first motor generator 110 becomes electric power for driving second motor generator 120 as it is. On the other hand, when the SOC of battery 150 is lower than a predetermined value, the electric power generated by first motor generator 110 is stored in battery 150.

- the power split mechanism 130 includes a planetary gear including a sun gear, a pinion gear, a carrier, and a ring gear.
- the pinion gear engages with the sun gear and the ring gear.
- the carrier supports the pinion gear so that it can rotate.
- the sun gear is connected to the rotation shaft of first motor generator 110.

- PM-ECU 174 has a function of managing EFI-ECU 170 and MG-ECU 172. For example, activation (power on) and stop (power off) of EFI-ECU 170 and MG-ECU 172 are controlled by a command signal from PM-ECU 174.
- PM-ECU 174 instructs EFI-ECU 170 on the target output and target torque of engine 100, and MG-ECU 172 generates power from first motor generator 110, drive power from second motor generator 120, and the like. Is commanded. Therefore, the PM-ECU 174 corresponds to a control device that comprehensively controls the power train of the vehicle. As an example, the PM-ECU 174 determines the driving torque of the vehicle according to the amount of operation of the accelerator pedal 180 by the user (also referred to as the accelerator opening), and implements the EFI-ECU 170 and the MG- so as to realize the determined driving torque. Commands are given to the ECU 172. The accelerator opening is detected by an accelerator opening sensor 182. The starting and stopping of PM-ECU 174 is managed by power supply ECU 176.
- the power supply ECU 176 determines whether or not the user (driver) has operated the start switch 178, generates an IG on signal or an IG off signal in accordance with the operation of the start switch 178 by the user, and sends it to the PM-ECU 174 Output. As an example, the power supply ECU 176 determines whether or not the user has operated the start switch 178 based on a voltage that changes as the user operates the start switch 178. Note that, as a method for determining whether or not the user has operated the start switch 178, a general method for determining whether or not the switch has been operated may be used. Do not repeat.
- power supply ECU 176 when the user operates start switch 178 while PM-ECU 174 is stopped, power supply ECU 176 generates an IG on signal. PM-ECU 174 is activated when an IG ON signal is input from power supply ECU 176.
- PM-ECU 174 maintains the activated state until IG off signal is continuously input from power supply ECU 176 and input for a predetermined standby time ⁇ T, and IG off signal is continued from power supply ECU 176. If it is input for a predetermined waiting time ⁇ T or longer, it stops.

- PM-ECU 174 is started when start switch 178 is operated to restart PM-ECU 174 after being stopped by operation of start switch 178.
- the driving torque of the vehicle is limited.
- the driving torque is reduced compared to a case where the driving torque is set to zero, is limited to an upper limit value or less, or the driving torque determined according to the accelerator opening is not limited.
- PM-ECU 174 releases the limitation of drive torque due to a decrease in the operation amount of accelerator pedal 180.

However, as shown in FIG. 5, the PM-ECU 174 stops the vehicle with the accelerator opening (or the throttle opening) exceeding a predetermined value. If you do, stop. As a result, when the driver stops, the limitation of the driving torque is released by releasing the foot from the accelerator pedal 180, and the vehicle can be prevented from starting unexpectedly due to the creep torque generated as a result.
