Abstract
An override module allowing a vehicle operator to default the status of an automated start-stop system to “off.” A first embodiment uses a module that is installed in-line with a manual override button. A second embodiment uses a module that is installed on the vehicle's CAN bus.
Claims15
A method for automatically overriding an automated engine start-stop feature in a vehicle having said automated engine start-stop feature implemented using a communication bus, comprising:
- (a) providing an override module in communication with said communication bus;
- (b) said override module monitoring said communication bus for a message indicating that a speed of said vehicle is zero;
- and
- (c) after detecting said message indicating that said speed of said vehicle is zero, said override module placing a brake status:
- off message on said communication bus and continuing to periodically place a brake status:
- off message on said communication bus until said override module detects a message on said communication bus indicating that said vehicle speed is above zero.
A method for automatically overriding an automated engine start-stop feature in a vehicle having said automated engine start-stop feature implemented using a communication bus, comprising:
- (a) providing an override module in communication with said communication bus;
- (b) said override module monitoring said communication bus for a message indicating that a speed of said vehicle is zero;
- (c) said override module reading a present value for a steering wheel angle of said vehicle from said communication bus;
- (d) said override module incrementing said present value for said steering wheel angle to create an incremented steering angle value;
- and
- (e) after detecting said message indicating that said speed of said vehicle is zero, said override module placing said incremented steering angle value on said communication bus.
A method for automatically overriding an automated engine start-stop feature in a vehicle having said automated engine start-stop feature implemented using a communication bus, comprising:
- (a) providing an override module in communication with said communication bus;
- (b) said override module monitoring said communication bus for a message indicating that a speed of said vehicle is zero;
- and
- (c) after detecting said message indicating that said speed of said vehicle is zero, said override module placing a user steering torque message on said communication bus.
A method for automatically overriding an automated engine start-stop feature in a vehicle having said automated engine start-stop feature implemented using a communication bus, comprising:
- (a) providing an override module in communication with said communication bus;
- (b) said override module monitoring said communication bus for a message indicating that a speed of said vehicle is zero;
- and
- (c) after detecting said message indicating that said speed of said vehicle is zero, said override module placing a climate control message on said communication bus, with said climate control message being interpreted by other controllers in communication with said communication bus to mean that heating or cooling of said vehicle is required.
A method for automatically overriding an automated engine start-stop feature in a vehicle having said automated engine start-stop feature implemented using a communication bus, comprising:
- (a) providing an override module in communication with said communication bus;
- (b) said override module monitoring said communication bus for a message indicating that a speed of said vehicle is zero;
- and
- (c) after detecting said message indicating that said speed of said vehicle is zero, said override module placing a low vehicle speed message on said communication bus.
A method for automatically overriding an automated engine start-stop feature in a vehicle having said automated engine start-stop feature implemented using a communication bus, comprising:
- (a) providing an override module in communication with said communication bus;
- (b) said override module monitoring said communication bus for a message indicating that a speed of said vehicle is zero;
- and
- (c) after detecting said message indicating that said speed of said vehicle is zero, said override module placing a low battery message on said communication bus.
