Abstract

A parking and stopping control system includes a park maintaining device configured to maintain a parked state; a park maintaining control device configured to control the park maintaining device to maintain the parked state; a parking temporary determining device capable of making a temporary determination that there is a possibility an own vehicle will be parked; and an intention determining device configured to determine an intention of a driver, wherein when the temporary determination is made, the park maintaining control device controls the park maintaining device to execute a maintaining control of the parked state if an intention of the driver is an intention to park, and the park maintaining control device prohibits the maintaining control of the parked state if the intention of the driver is not the intention to park.

First claim

The invention claimed is:

1. A parking and stopping control system comprising:
an electrical parking brake configured to maintain a parked state of a vehicle;
circuitry including a first device, a second device, a third device, a fourth device, and a fifth device; and
a display unit, wherein
the fourth device includes a braking force generating device configured to maintain a stopped state of the vehicle by controlling a magnitude of a braking force of the braking force generating device,
the fifth device is configured to control the fourth device to maintain the stopped state of the vehicle when the vehicle is stopped,
the first device is configured to control the electrical parking brake to maintain the parked state of the vehicle,
the second device is configured to make a temporary determination that there is a possibility an own vehicle will be parked when a parking condition is established,
the display unit is configured to transmit intention confirming information to prompt a driver to confirm the intention to park when the temporary determination is made,
the third device is configured to determine an intention of the driver to park,
during the maintaining control of the stopped state, when the driver operates an intention expressing device in response to the intention confirming information output by the display unit to confirm that the driver intends to park, the first device controls the electrical parking brake to maintain the parked state, and
when the driver operates the intention expressing device in response to the intention confirming information output by the display unit to confirm that the driver does not intend to park, the first device prohibits the electrical parking brake from maintaining the parked state.

2. The parking and stopping control system according to claim 1 , wherein if the intention of the driver is not the intention to park, the third device again determines the intention of the driver after elapse of a predetermined time.

3. The parking and stopping control system according to claim 1 , wherein if the intention of the driver is not the intention to park, the third device determines necessity of redetermination of the intention of the driver, and the intention of the driver is again determined after elapse of a predetermined time if it is determined that redetermination is necessary.

4. The parking and stopping control system according to claim 1 , wherein if the maintaining control of the parked state is being executed, the first device releases the maintaining control of the parked state if the temporary determination is not made and the intention of the driver is the intention to release the maintaining control of the parked state.

5. The parking and stopping control system according to claim 1 , wherein the second device is configured to make the temporary determination when a signal indicating the driver getting off is detected during the maintaining control of the stopped state.

6. The parking and stopping control system according to claim 1 , wherein the third device controls the display unit to transmit the intention confirming information to the driver to confirm the intention to park when the second device makes the temporary determination.

7. The parking and stopping control system according to claim 1 , wherein the intention confirming information refers to an information for confirming an intention of the driver to park the vehicle.

8. The parking and stopping control system according to claim 1 , wherein if the driver does not operate the intention expressing device after the display unit outputs the intention confirming information so that it is not determined that the driver intends to park, the first device prohibits the electrical parking brake from maintaining the parked state without any operation by the driver.
