Abstract
While an ordinary moving assist control is executed, a vehicle driving assist apparatus stops the ordinary moving assist control and execute an ordinary moving control to accelerate an own vehicle, based on an accelerator pedal operation amount when an accelerator override state is produced due to an operation of an accelerator pedal of the own vehicle. While an economy moving assist control is executed, the vehicle driving assist apparatus accelerates the own vehicle by an optimum acceleration control when an acceleration request condition that the accelerator override state is produced, is satisfied.
Claims10
A vehicle driving assist apparatus comprising an electronic control unit configured to execute an ordinary moving assist control and an economy moving assist control,
- the ordinary moving assist control being a control to autonomously accelerate and decelerate an own vehicle so as to maintain a moving speed of the own vehicle at a set speed, or maintain a distance between the own vehicle and a preceding vehicle which moves ahead of the own vehicle at a set distance,
- the economy moving assist control being a control to autonomously accelerate and decelerate the own vehicle so as to maintain the moving speed of the own vehicle within a predetermined speed range, or maintain the distance between the own vehicle and the preceding vehicle within a predetermined forward distance range,
- the electronic control unit being configured to:
- while the economy moving assist control is executed,
- execute (i) a coasting control to decelerate the own vehicle by causing the own vehicle to coast and (ii) an optimum acceleration control to accelerate the own vehicle by controlling operations of a driving apparatus of the own vehicle at a power output efficiency of the driving apparatus equal to or greater than a predetermined efficiency;
- and
- while the ordinary moving assist control is executed,
- stop the ordinary moving assist control and execute an ordinary moving control to accelerate the own vehicle, based on an accelerator pedal operation amount when an accelerator override state is produced due to an operation of an accelerator pedal of the own vehicle,
- wherein the electronic control unit is configured to accelerate the own vehicle by the optimum acceleration control when an acceleration request condition that the accelerator override state is produced, is satisfied while the economy moving assist control is executed.
A vehicle driving assist method comprising steps of:
- executing an ordinary moving assist control to autonomously accelerate and decelerate an own vehicle so as to maintain a moving speed of the own vehicle at a set speed, or maintain a distance between the own vehicle and a preceding vehicle which moves ahead of the own vehicle at a set distance;
- executing an economy moving assist control to autonomously accelerate and decelerate the own vehicle so as to maintain the moving speed of the own vehicle within a predetermined speed range, or maintain the distance between the own vehicle and the preceding vehicle within a predetermined forward distance range;
- while the economy moving assist control is executed,
- executing a coasting control to decelerate the own vehicle by causing the own vehicle to coast and an optimum acceleration control to accelerate the own vehicle by controlling operations of a driving apparatus of the own vehicle at a power output efficiency of the driving apparatus equal to or greater than a predetermined efficiency;
- while the ordinary moving assist control is executed,
- stopping the ordinary moving assist control and executing an ordinary moving control to accelerate the own vehicle, based on an accelerator pedal operation amount when an accelerator override state is produced due to an operation of an accelerator pedal of the own vehicle;
- and
- accelerating the own vehicle by the optimum acceleration control when an acceleration request condition that the accelerator override state is produced, is satisfied while the economy moving assist control is executed.
A vehicle driving assist program configured to:
- execute an ordinary moving assist control to autonomously accelerate and decelerate an own vehicle so as to maintain a moving speed of the own vehicle at a set speed, or maintain a distance between the own vehicle and a preceding vehicle which moves ahead of the own vehicle at a set distance;
- execute an economy moving assist control to autonomously accelerate and decelerate the own vehicle so as to maintain the moving speed of the own vehicle within a predetermined speed range, or maintain the distance between the own vehicle and the preceding vehicle within a predetermined forward distance range;
- while the economy moving assist control is executed,
- execute a coasting control to decelerate the own vehicle by causing the own vehicle to coast and an optimum acceleration control to accelerate the own vehicle by controlling operations of a driving apparatus of the own vehicle at a power output efficiency of the driving apparatus equal to or greater than a predetermined efficiency;
- while the ordinary moving assist control is executed,
- stop the ordinary moving assist control and execute an ordinary moving control to accelerate the own vehicle, based on an accelerator pedal operation amount when an accelerator override state is produced due to an operation of an accelerator pedal of the own vehicle;
- and
- accelerate the own vehicle by the optimum acceleration control when an acceleration request condition that the accelerator override state is produced, is satisfied while the economy moving assist control is executed.
