Abstract
The invention relates to a device for increasing the security of a motor vehicle comprising an automatic transmission, which is impinged upon by an electrical transmission control system and a detection unit for detecting a critical driving situation and for generating a corresponding signal. In order to increases driving security, an evaluation device is provided which checks whether the generated signal has reached a specific value or exceeded a specific threshold. If said value has been reached or the threshold has been exceeded, the evaluation device causes the transmission control system to interrupt the positive engagement of the transmission.
Claims19
A device for increasing security of a motor vehicle, comprising:
- an automatic transmission;
- an electric transmission control operatively coupled with the automatic transmission;
- a detection device that detects a parameter of one of an accident and swerving event of the vehicle and generates a signal corresponding to the parameter;
- an analyzing device that evaluates whether the signal reaches a specific value or exceeds a specific threshold corresponding to presence of the accident or swerving event, said analyzing device causing the electric transmission control to interrupt a positive engagement of the automatic transmission by shifting the automatic transmission into a neutral position when the specific value is reached or the specific threshold is exceeded.
A method for increasing security of a vehicle having an automatic transmission operatively coupled with an electric transmission control, the method comprising the acts of:
- detecting one of an accident and a swerving event of the vehicle;
- generating a signal value associated with the accident or swerving event;
- evaluating the signal value to determine whether it reaches a specific value or exceeds a specific threshold;
- and
- interrupting the positive engagement of the automatic transmission by shifting the automatic transmission into a neutral position when the specific value is reached or the specific threshold is exceeded.
