Abstract
An electronic control unit of a hybrid vehicle is configured to determine whether or not parking operation of the hybrid vehicle is being performed. The electronic control unit is configured to control the engine and the rotary electric machine such that starting the engine when the parking operation of the hybrid vehicle is being performed is harder than starting the engine when the parking operation of the hybrid vehicle is not being performed.
Claims15
A hybrid vehicle comprising:
- a battery;
- an engine;
- a rotary electric machine electrically connected to the battery, the rotary electric machine mechanically connected to the engine;
- and
- an electronic control unit configured to
- (i) determine whether or not parking operation of the hybrid vehicle is being performed, and
- (ii) control the engine and the rotary electric machine such that starting the engine when the parking operation of the hybrid vehicle is being performed is harder than starting the engine when the parking operation of the hybrid vehicle is not being performed.
4 more elements
A hybrid vehicle comprising:
- a battery;
- an engine configured to output power;
- a rotary electric machine electrically connected to the battery, the rotary electric machine mechanically connected to the engine;
- an air conditioner configured to be driven with power from the battery;
- and
- an electronic control unit configured to
- (i) perform parking assistance control for causing the hybrid vehicle to travel to a target parking position when a parking assistance request is issued from a user,
- (ii) perform control for starting the engine when a required power required for the hybrid vehicle including electric power required for driving the air conditioner is equal to or greater than a start threshold value, and
- (iii) perform control for prohibiting driving of the air conditioner when the parking assistance control is being performed.
6 more elements
A hybrid vehicle comprising:
- a battery;
- an engine configured to output power;
- a rotary electric machine electrically connected to the battery, the rotary electric machine mechanically connected to the engine;
- and
- an electronic control unit configured to
- (i) perform control for causing the hybrid vehicle to travel while switching between a charge depleting mode and a charge sustaining mode,
- (ii) perform parking assistance control for causing the hybrid vehicle to travel to a target parking position when a parking assistance request is issued from a user, and
- (iii) select the charge depleting mode when the parking assistance control is being performed.
5 more elements
A hybrid vehicle comprising:
- a battery;
- an engine configured to output power;
- a rotary electric machine electrically connected to the battery, the rotary electric machine mechanically connected to the engine;
- and
- an electronic control unit configured to
- (i) perform parking assistance control for causing the hybrid vehicle to travel to a target parking position when a parking assistance request is issued from a user,
- (ii) perform control for causing the rotary electric machine to generate power with a driving force from the engine and charging the battery when a value indicating a state of charge of the battery is less than a threshold value,
- (iii) store a point at which the parking assistance control has been performed as an assistance history point, and
- (iv) perform control for charging the battery when a distance between the assistance history point and the hybrid vehicle is equal to or less than a predetermined distance such that the value indicting the state of charge of the battery when the hybrid vehicle reaches the assistance history point is equal to or greater than a predetermined value obtained by adding an amount of power required for the parking assistance control to the threshold value.

A control method for a hybrid vehicle, the hybrid vehicle including,
- a battery,
- an engine,
- a rotary electric machine electrically connected to the battery, the rotary electric machine mechanically connected to the engine, and
- an electronic control unit,
- the control method comprising
- (i) determining, by the electronic control unit, whether or not parking operation of the hybrid vehicle is being performed, and
- (ii) controlling, by the electronic control unit, the engine and the rotary electric machine such that starting the engine when the parking operation of the hybrid vehicle is being performed is harder than starting the engine when the parking operation of the hybrid vehicle is not being performed.
