Method and system for warning a driver of a motor vehicle

A method for warning a driver of a first motor vehicle including at least one sensor for detecting a potentially hazardous condition, an automatic transmission and a controller, said method comprising:

• detecting, with the at least one sensor, a second vehicle approaching the first vehicle from behind;
• and
• alerting the driver by directing the transmission, with the controller, to perform a transmission operation that generates an acceleration when the second vehicle is detected.

A method for warning a driver of a motor vehicle including at least one sensor for detecting a potentially hazardous condition, an automatic transmission and a controller connected to the at least one sensor and the transmission, said method comprising:

• detecting a potentially hazardous condition with the at least one sensor;
• and
• alerting the driver by directing the transmission, with the controller, to perform at least two transmission operations, the transmission operations generating an acceleration or a deceleration, when the potentially hazardous condition is detected with the at least one sensor.

A control system for a motor vehicle with an automatic transmission comprising:

• at least one sensor configured to detect a potentially hazardous condition;
• and
• a controller configured to direct the automatic transmission to perform a first transmission operation if the potentially hazardous condition is detected, wherein the controller is further configured to direct the transmission to perform a second transmission operation shortly after the first transmission operation.

A method for warning a driver of a motor vehicle including at least one sensor, a controller and an automatic transmission having a torque converter with a lockup clutch, said method comprising:

• detecting a potentially hazardous condition with the at least one sensor;
• and
• alerting the driver, when the potentially hazardous condition is detected, by directing the transmission, with the controller, to lock or unlock the lockup clutch to generate an acceleration or deceleration.
