Automatic reverse brake assist system
First Claim
1. A method of deactivating, via an electronic controller, a vehicle brake system that had been previously automatically activated in response to detection by a first sensor of an object in the intended path of the vehicle, comprising:
- detecting, via a second sensor, when motion of the vehicle has stopped;
determining whether to cause deactivation of the vehicle brakes in response to the second sensor; and
automatically deactivating the vehicle brakes a pre-determined period of time after the motion of the vehicle has stopped, wherein the pre-determined period of time includes a duration to complete the determining step.

Abstract
An automotive vehicle braking system and method for controlling the same. The system includes an electronic controller communicatively coupled to a vehicle braking system and a vehicle motion detection device. The braking system is configured to be automatically activated in response to detection of an object in a path of the vehicle. Once activated, the braking system is deactivated either by the driver or a pre-determined time period after detection that motion of the vehicle has stopped. Prior to deactivation of the vehicle braking system an HMI message is activated indicating imminent deactivation of the vehicle braking system.

5. A braking system for an automotive vehicle, comprising:
-
an electronic controller communicatively coupled to a vehicle brake system and a vehicle motion detection device; said electronic controller configured to; cause said vehicle brake system to be automatically activated in response to receiving a signal indicative of an object being detected in a path of the vehicle; receive a signal from said vehicle motion detection device indicative that rearward motion of the vehicle has stopped; determine whether to cause deactivation of said vehicle brake system in response to receiving said signal from said motion detection device; and communicate with said brake system so as to deactivate application of said brake system a pre-determined amount of time after receiving said signal indicative that motion of the vehicle has stopped, wherein said pre-determined amount of time includes a duration said electronic controller takes to determine whether to cause deactivation of said vehicle brake system. - View Dependent Claims (6, 7, 8, 9, 10)

11. A method of controlling, via an electronic controller, an automatic braking system for an automotive vehicle, comprising:
-
detecting, via a first sensor, an object in a path of the vehicle; automatically applying the braking system to stop motion of the vehicle; detecting, via a second sensor, when the motion of the vehicle has stopped; determining whether to release the vehicle braking system in response to the second sensor; and releasing the vehicle braking system a pre-determined period of time after the motion of the vehicle has stopped, wherein the pre-determined period of time includes a duration the determining step takes to complete. - View Dependent Claims (12, 13, 14)
