PCT No. PCT/NZ93/00110 Sec. 371 Date Jul. 12, 1995 Sec. 102(e) Date Jul. 12, 1995 PCT Filed Nov. 11, 1993 PCT Pub. No. WO94/11221 PCT Pub. Date May 26, 1994Apparatus for the monitoring of the accelerator pedal in order to provide an early warning braking system and/or method therefor. The apparatus uses a detection mechanism to generate a signal representative of the pressure or force applied to the accelerator of the vehicle and utilizes a monitoring mechanism to monitor the signals provided by the detection mechanism. Also present are comparison and calculation devices to compare the monitored signals from the monitoring mechanism and to calculate the rate of change of pressure or force applied to the accelerator. There is a second comparison device to compare the rate of change in pressure or force on the accelerator with a pre-set limit signalling device operatively connected to the comparison device such that the signalling device is activated when the rate of change of pressure or force applied to the accelerator is above or alternatively below the pre-set limit. A variety of other comparisons are provided including at least one to filter out the effects of gear changes.
