Abstract
Abstract The invention provides an accessory for a vehicle, the accessory having a sensor for sensing the acceleration of the vehicle, the speed of the vehicle or the operating speed of an engine of the vehicle, a first recorder for recording when any of these parameters is excessive, detectors for detecting whether the vehicle is in motion or the engine is in operation and a second recorder for recording the amount of time the vehicle is in motion or the engine is in operation. The accessory is electrically operable, the speed of the vehicle and of the engine being sensed by electro-magnetic devices in co-operation with magnetized elements whose speed of rotation is proportional to the speed of the vehicle or its engine. Conveniently, the acceleration of the vehicle is determined by differentiating a signal representative of the vehicle's speed. The accessory further includes a visual or aural alarm for warning a driver of the vehicle that an abuse condition has occurred or is about to occur.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
229 words
An accessory for a vehicle having a drive means, the accessory including a vehicle speed sensing means for sensing the travelling speed of the vehicle and for providing a vehicle speed signal; a differentiating means for differentiating the vehicle speed signal with respect to time to provide an acceleration signal representative of the linear acceleration of the vehicle; a vehicle overspeed recording means responsive to the vehicle speed sensing means for recording the amount of time that the vehicle is driven at a speed greater than a predetermined speed; a vehicle excessive acceleration recording means responsive to the differentiating means for recording the amount of time that the vehicle is accelerated at an acceleration greater than a predetermined value; a vehicle operating time recording means responsive to the vehicle speed sensing means for recording the amount of time the vehicle is in motion; a drive means operating speed sensing means for sensing the operating speed of the drive means and for providing a drive means speed signal; a drive means overspeed recording means responsive to the drive means speed sensing means for recording the amount of time that the drive means is operated at a speed greater than a predetermined speed; and a drive means operating time recording means responsive to the drive means speed sensing means for recording the amount of time the drive means is in operation.
Claim 2
Dependent Claim
229 words
An accessory for a vehicle having a drive means, the accessory including a vehicle speed sensing means for sensing the travelling speed of the vehicle and for providing a vehicle speed signal; a differentiating means for differentiating the vehicle speed signal with respect to time to provide an acceleration signal representative of the linear acceleration of the vehicle; a vehicle overspeed recording means responsive to the vehicle speed sensing means for recording the amount of time that the vehicle is driven at a speed greater than a predetermined speed; a vehicle excessive acceleration recording means responsive to the differentiating means for recording the amount of time that the vehicle is accelerated at an acceleration greater than a predetermined value; a vehicle operating time recording means responsive to the vehicle speed sensing means for recording the amount of time the vehicle is in motion; a drive means operating speed sensing means for sensing the operating speed of the drive means and for providing a drive means speed signal; a drive means overspeed recording means responsive to the drive means speed sensing means for recording the amount of time that the drive means is operated at a speed greater than a predetermined speed; and a drive means operating time recording means responsive to the drive means speed sensing means for recording the amount of time the drive means is in operation.
Claim 3
Dependent Claim
53 words
An accessory as claimed in claim 1 which includes a vehicle overspeed indicating means responsive to the vehicle speed sensing means for indicating to an operator of the vehicle that the vehicle is being driven at a speed greater than a second predetermined speed, which is less than the said predetermined vehicle speed.
Claim 4
Dependent Claim
42 words
An accessory as claimed in claim 1, which includes a vehicle excessive acceleration indicating means responsive to the differentiating means for indicating to an operator of the vehicle that the vehicle is being accelerated at an acceleration greater than the predetermined value.
Claim 5
Dependent Claim
57 words
An accessory as claimed in claim 1 which includes a drive means overspeed indicating means responsive to the drive means speed sensing means for indicating to an operator of the vehicle that the drive means is being operated at a speed greater than a second predetermined speed, which is less than the said predetermined drive means speed.
Claim 6
Dependent Claim
26 words
An accessory as claimed in claim 1 in which the vehicle speed sensing means provides and electrical output signal and the differentiating means is electrically operable.
Claim 7
Dependent Claim
44 words
An accessory as claimed in claim 1 in which the vehicle overspeed recording means, the vehicle excessive acceleration recording means, the vehicle operating time recording means, the drive means overspeed recording means and the drive means operating time recording means are all electrically operable.
Claim 8
Dependent Claim
30 words
An accessory as claimed in claim 1 in which the vehicle overspeed recording means, the vehicle excessive acceleration recording means and the drive means overspeed recording means are digitally operable.
