Abstract

An automatic braking system for a vehicle includes a sensor system configured to detect the previous speed of the vehicle, occupancy of a driver's seat of the vehicle, and an input to at least one of an accelerator pedal of the vehicle and a brake pedal of the vehicle. The automatic braking system also includes a control module communicatively connected to the sensor system and configured to automatically brake the vehicle when the vehicle was previously stopped, the driver's seat is occupied, and there is no input to the accelerator pedal or the brake pedal.

Claims (41)

1. An automatic braking system for a vehicle, comprising:

a sensor system configured to detect a previous speed of the vehicle, occupancy of a driver's seat of the vehicle, a position of a transmission of the vehicle, and an input to at least one of an accelerator pedal of the vehicle and a brake pedal of the vehicle; and

a control module communicatively connected to the sensor system and configured to automatically brake the vehicle when the vehicle was previously stopped, the driver's seat is occupied, and there is no input to the accelerator pedal or the brake pedal, and to automatically brake the vehicle when the vehicle was previously stopped, the driver's seat is not occupied, and the transmission is not in park.

2. The automatic braking system of claim 1 , wherein the sensor system is further configured to detect information about an external environment of the vehicle, and wherein the control module is configured to determine, using the information about the external environment, whether the vehicle is exiting a parking space.

3. The automatic braking system of claim 2 , wherein the control module is configured to automatically brake the vehicle when the vehicle was previously stopped, the driver's seat is occupied, there is no input to the accelerator pedal or the brake pedal, and the vehicle is not exiting a parking space.

4. The automatic braking system of claim 2 , wherein the control module is configured to allow the vehicle to roll when the vehicle was previously stopped, the driver's seat is occupied, there is no input to the accelerator pedal or the brake pedal, and the vehicle is exiting a parking space.

5. The automatic braking system of claim 1 , wherein the control module is configured to allow the vehicle to roll when the vehicle was previously stopped, the driver's seat is occupied, and there is an input to the accelerator pedal or the brake pedal.

6. The automatic braking system of claim 1 , wherein the sensor system includes vehicle sensors, and wherein the vehicle sensors include a speedometer configured to detect the previous speed of the vehicle, an occupant detection sensor configured to detect occupancy of the driver's seat, the occupant detection sensor being at least one of a weight sensor and a camera, an accelerator pedal input sensor configured to detect an input to the accelerator pedal, and a brake pedal input sensor configured to detect an input to the brake pedal.

7. The automatic braking system of claim 1 , wherein the sensor system includes vehicle sensors, and wherein the vehicle sensors include a transmission position sensor configured to detect the position of a transmission of the vehicle.

8. The automatic braking system of claim 2 , wherein the sensor system includes external environment sensors configured to detect the information about the external environment, and wherein the external environment sensors include at least one of a camera and a distance sensor.

9. A method for operating an automatic braking system of a vehicle, comprising:

detecting whether the vehicle was previously stopped;

detecting whether a driver's seat of the vehicle is occupied;

detecting whether there is an input to at least one of an accelerator pedal of the vehicle and a brake pedal of the vehicle;

detecting a position of a transmission of the vehicle;

automatically braking the vehicle when the vehicle was previously stopped, the driver's seat is occupied, and there is no input to the accelerator pedal or the brake pedal; and

automatically braking the vehicle when the vehicle was previously stopped, the driver's seat is not occupied, and the transmission is not in park.

10. The method of claim 9 , further comprising:

detecting information about an external environment of the vehicle; and

determining, using the information about the external environment of the vehicle, whether the vehicle is exiting a parking space.

11. The method of claim 10 , further comprising:

automatically braking the vehicle when the vehicle was previously stopped, the driver's seat is occupied, there is no input to the accelerator pedal or the brake pedal, and the vehicle is not exiting a parking space.

12. The method of claim 10 , further comprising:

allowing the vehicle to roll when the vehicle was previously stopped, the driver's seat is occupied, there is no input to the accelerator pedal or the brake pedal, and the vehicle is exiting a parking space.

13. The method of claim 9 , further comprising:

allowing the vehicle to roll when the vehicle was previously stopped, the driver's seat is occupied, and there is an input to the accelerator pedal or the brake pedal.

14. A non-transitory computer-readable medium including instructions that, when executed by a processor, cause the processor to:

detect, using sensor data about a vehicle:

whether the vehicle was previously stopped;

whether a driver's seat of the vehicle is occupied;

whether there is an input to at least one of an accelerator pedal of the vehicle and a brake pedal of the vehicle; and

a position of a transmission of the vehicle;

automatically brake the vehicle when the vehicle was previously stopped, the driver's seat is occupied, and there is no input to the accelerator pedal or the brake pedal; and

automatically braking the vehicle when the vehicle was previously stopped, the driver's seat is not occupied, and the transmission is not in park.

15. The non-transitory computer-readable medium of claim 14 , wherein the instructions further cause the processor to:

detect information about an external environment of the vehicle; and

determine, using the information about the external environment of the vehicle, whether the vehicle is exiting a parking space.

16. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the processor to:

automatically brake the vehicle when the vehicle was previously stopped, the driver's seat is occupied, there is no input to the accelerator pedal or the brake pedal, and the vehicle is not exiting a parking space.

17. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the processor to:

allow the vehicle to roll when the vehicle was previously stopped, the driver's seat is occupied, there is no input to the accelerator pedal or the brake pedal, and the vehicle is exiting a parking space.
