摘要: When the gearshift position SP is the N position and the accumulated charge ratio SOC of the battery is less than or equal to the threshold value Slow (step S120), the engine is cranked by a first motor (the motor MG1) and started in the case that the vehicle stop is held (steps S140 and s150). After the engine is started, the shutoff of the inverter for driving the motor MG1 is performed and the self-sustained operation of the engine is performed at the rotation speed N1 at which the back electromotive force generated on the motor MG1 is more than the voltage applied to the inverters (steps S180 to S200).

摘要: A hybrid vehicle illustrated as a representative example of an electrically-powered vehicle includes a chargeable/dischargeable power storage device, a motor configured to generate a vehicle drive force by receiving supply of power from the power storage device, an internal combustion engine as a drive force source, and a generator configured to generate charging power for the power storage device by power generation using an output of the internal combustion engine. If the generator cannot be operated normally, the control unit causes the electrically-powered vehicle to perform limp-home mode traveling by traveling using only the motor. During the limp-home mode traveling, the control device calculates a remaining travelable distance in the limp-home mode traveling, based on at least a remaining capacity of the power storage device and a vehicle speed.

摘要: An ECU determines whether or not there is an abnormality (shift pattern abnormality) in a combination of shift signals provided from a shift position sensor. After occurrence of the shift pattern abnormality is determined, ECU determines whether or not a first condition that a shift pattern has changed into a normal pattern of a drive range, a second condition that a brake is ON and a vehicle is in a stop state is satisfied, and a third condition that an accelerator is OFF are satisfied. When occurrence of the shift pattern abnormality is determined, ECU stops generation of driving force of the vehicle and prohibits switching to the drive range. When ECU determines that the above-mentioned first to third conditions are satisfied after occurrence of the shift pattern abnormality is determined, ECU switches the shift range to the drive range indicated by the shift pattern.

摘要: During the deactivation of a driving system of a vehicle, an ECU determines whether or not a P range abnormality occurs which exhibits that a shift signal transmitted from a shift position sensor includes a P signal and an MJ signal corresponding to the P range as well as a different-type signal other than the P signal and the MJ signal. When the P range abnormality occurs, the ECU determines whether or not the vehicle-stopped state can be assured based on whether or not a brake-ON state (a hydraulic braking force or a parking braking force are beyond the range capable of maintaining vehicle-stopped state) is present. In a case where a P range abnormality occurs, when ECU determines that the vehicle-stopped state can be assured, the ECU allows the activation of the driving system.

摘要: An ECU includes a collision determination unit, a condition determination unit, and an output suppression unit. The collision determination unit monitors an acceleration detected by a collision sensor, and determines that a vehicle collision has occurred when the acceleration is greater than a predetermined value. The condition determination unit determines whether or not a vehicular speed absolute value is smaller than a threshold vehicular speed in a determination period lasting from the determination of collision for a predetermined time. The output suppression unit suppresses an output of a vehicle driving force when the vehicular speed absolute value is smaller than the threshold vehicular speed in the determination period.

After occurrence of the shift pattern abnormality is determined, the ECU determines whether or not a first condition that a shift pattern changes into a normal pattern of a drive range is satisfied, and whether or not a second condition that a vehicle is running (a driver has an intention to cause the vehicle to run) is satisfied.

When the above-mentioned first condition and second condition are satisfied after occurrence of the shift pattern abnormality is determined, the ECU switches the shift range to the drive range indicated by the shift pattern and recovers the driving force.
