Abstract

A system and method of immobilizing a vehicle include receiving a driver presence signal and a transmission state signal and commanding a transmission tie-up in response to the driver presence signal and the transmission state signal. In one embodiment, controlling a transmission element to tie-up a transmission includes braking approximately simultaneously a combination of transmission elements to inhibit rotation of a transmission output and maintaining transmission line pressure to maintain the transmission tie-up when an engine is off.

Description

technical field [0001] The present disclosure relates to a method and system for immobilizing a vehicle. Background technique [0002] A distracted driver may leave the vehicle without operating the automatic transmission without placing the vehicle in park and stopping the vehicle, which may result in unexpected vehicle motion. Some vehicles use systems that monitor for excessive acceleration or driver presence after starting the engine with the gear lever in the non-drive position. If the gear lever is moved into the Drive position, the system activates a timer to deliver a signal for a predetermined period of time. This signal is used to shut down the engine if the acceleration or throttle measuring device indicates that excessive acceleration has occurred, or if the seat sensor device indicates that the driver is not present. [0003] Another system uses emergency braking and engine shutdown switches. The microprocessor monitors the weight sensor and speed sensor, and...
