Vehicle deceleration assistance apparatus and method, and computer-readable storage medium storing vehicle deceleration assistance program
A vehicle deceleration assistance apparatus executes a deceleration assistance control before a vehicle arrives at a target point. The apparatus executes the deceleration assistance control, setting a deceleration assistance level to a first level when a first condition is satisfied, blinkers are activated, and a second condition is satisfied. The first condition is a condition that a target point distance between the vehicle and the target point is equal to or shorter than a first distance. The second condition is a condition that the target point distance is equal to or longer than a second distance shorter than the first distance. The apparatus executes the deceleration assistance control, setting the deceleration assistance level to a second level lower than the first level when the first condition is satisfied, the blinkers are activated, and the second condition is not satisfied.
1. A vehicle deceleration assistance apparatus, comprising an electronic control unit configured to execute a deceleration assistance control to assist a deceleration of a vehicle before the vehicle arrives at a deceleration assistance target point where the vehicle can turn left or right,
wherein the electronic control unit is configured to:
execute the deceleration assistance control, setting a deceleration assistance level of assisting the deceleration of the vehicle by the deceleration assistance control to a first level when a first condition is satisfied, blinkers of the vehicle are activated, and a second condition is satisfied,
the first condition being a condition that a target point distance between the vehicle and the deceleration assistance target point is equal to or shorter than a first distance,
the second condition being a condition that the target point distance is equal to or longer than a second distance shorter than the first distance; and
execute the deceleration assistance control, setting the deceleration assistance level to a second level lower than the first level when the first condition is satisfied, the blinkers are activated, and the second condition is not satisfied.
2. The vehicle deceleration assistance apparatus as set forth in claim 1 , wherein the electronic control unit is configured to increase the second distance when the first condition is satisfied, the blinkers are activated, and a traffic light ahead of the vehicle lights a yellow light.
3. The vehicle deceleration assistance apparatus as set forth in claim 1 , wherein the electronic control unit is configured to increase the second distance when the first condition is satisfied, the blinkers are activated, and there is an entrance of a parking lot over the deceleration assistance target point.
4. The vehicle deceleration assistance apparatus as set forth in claim 1 , wherein the electronic control unit is configured to execute the deceleration assistance control, setting the deceleration assistance level to a third level lower than the first level when the first condition is not satisfied, and the blinkers are activated.
5. The vehicle deceleration assistance apparatus as set forth in claim 4 , wherein the electronic control unit is configured to increase the first distance such that the first distance for a higher moving speed of the vehicle is longer than the first distance for the lower moving speed of the vehicle.
6. A vehicle deceleration assistance method of executing a deceleration assistance control to assist a deceleration of a vehicle before the vehicle arrives at a deceleration assistance target point where the vehicle can turn left or right,
wherein the vehicle deceleration assistance method comprises steps of:
executing the deceleration assistance control, setting a deceleration assistance level of assisting the deceleration of the vehicle by the deceleration assistance control to a first level when a first condition is satisfied, blinkers of the vehicle are activated, and a second condition is satisfied,
the first condition being a condition that a target point distance between the vehicle and the deceleration assistance target point is equal to or shorter than a first distance,
the second condition being a condition that the target point distance is equal to or longer than a second distance shorter than the first distance; and
executing the deceleration assistance control, setting the deceleration assistance level to a second level lower than the first level when the first condition is satisfied, the blinkers are activated, and the second condition is not satisfied.
7. A non-transitory computer-readable storage medium storing vehicle deceleration assistance executable instructions configured to execute a deceleration assistance control to assist a deceleration of a vehicle before the vehicle arrives at a deceleration assistance target point where the vehicle can turn left or right,
wherein the vehicle deceleration assistance executable instructions stored on the computer-readable storage medium are configured to:
execute the deceleration assistance control, setting a deceleration assistance level of assisting the deceleration of the vehicle by the deceleration assistance control to a first level when a first condition is satisfied, blinkers of the vehicle are activated, and a second condition is satisfied,
the first condition being a condition that a target point distance between the vehicle and the deceleration assistance target point is equal to or shorter than a first distance,
the second condition being a condition that the target point distance is equal to or longer than a second distance shorter than the first distance; and
execute the deceleration assistance control, setting the deceleration assistance level to a second level lower than the first level when the first condition is satisfied, the blinkers are activated, and the second condition is not satisfied.
