Automotive driving pattern monitor
First Claim
1. A system for use in connection with an automotive vehicle having a brake pedal supported by a pivotal flange arm, comprising:
- a pressure sensor affixed to the pedal operative to provide a continuous analog output signal as a function of the instantaneous pressure applied to said pedal;
an audio output device connected to the brake pedal flange arm;
a memory storing a table of preset operating parameters; and
a controller, operative to receive signals from said pressure sensor and to control the generation of output signals by the audio output device as a function of the sensor signals and of values stored in said memory to provide one of a plurality of audio output signals.

Abstract
A system for sensing the manner of operation of an automotive vehicle and for generating feedback signals to the vehicle operator as a function of the manner of operation includes a pressure sensor connected to the brake pedal so as to generate a multi-state output signal as a function of the instantaneous pressure applied to the brake, and a plurality of acceleration sensors supported so as to sense the rate of change of the motion about different axes. The sensor output signals are all provided to a controller which compares their outputs to values stored in a table to generate one of a stored set of output values. An audio signal generator receives the output values and generates an audio feedback signal to the vehicle operator as a function of the status of the sensors. The system may also provide a signal to the vehicle engine to prevent operation of the vehicle when excessively erratic operation is detected.

7. A system for use in connection with an automotive vehicle having a brake pedal, comprising:
-
a pressure sensor affixed to the pedal operative to provide an output signal having a value which is a function of the instantaneous pressure applied to the pedal; a plurality of inertia sensors supported on the vehicle, said sensors including a first sensor supported to detect acceleration along an axis normal to the longitudinal axis of the vehicle, and second and third sensors supported to detect acceleration along axes normal to each other and in the plane of the longitudinal axis of the vehicle; a memory storing a table of output signals versus signals from said brake sensor and said inertia sensors; a controller connected to receive the signals from said brake sensor and said inertia sensors and to use the said memory table to generate one of a plurality of output states; and a driver warning device operative to generate one of a plurality of signals as a function of the outputs of the controller.
