Abstract

A vehicle speed control memory system includes a microprocessor for storing various operator selected vehicle speed settings in memory thus allowing the operator to set the various speeds for the cruise control system, and then as the vehicle enters different speed limit zones, such as would occur on long trips through both rural and urban areas, the operator can increase or decrease vehicle speed by actuating the appropriate memory buttons corresponding to the previously selected vehicle speed settings for achieving and maintaining the desired speed.

Claims

1. A speed memory system for use with the cruise control system of an automotive vehicle for maintaining the desired vehicle speed through the cruise control system while passing through different speed limit zones, comprising:

a control module including a microprocessor and a memory unit that are electrically interconnected;

a speed memory system panel mounted on the steering wheel of the automotive vehicle;

the speed memory system panel having a plurality of speed set buttons with each speed set button for setting a discrete vehicle speed setting, and a plurality of memory buttons with each memory button interconnected through the control module to the corresponding speed set button so that pressing the respective memory button initiates the speed setting of the corresponding speed set button; and

after the selected speed set buttons have been set and the cruise control system engaged, the desired vehicle speed can be attained by engaging the appropriate memory buttons as the automotive vehicle enters and leaves the different speed limit zones.

2. The speed memory system for use with the cruise control of an automotive vehicle of claim 1 further comprising a vehicle speed sensor for continuously sensing the vehicle speed and transmitting the vehicle speed as a system input to the control module.

3. The speed memory system for use with the cruise control of an automotive vehicle of claim 2 further comprising a tachometer that provides engine rpm input values to the control module.

4. The speed memory system for use with the cruise control of an automotive vehicle further comprising an accelerator feedback position that provides input values to the control module so that the control module can evaluate the vehicle speed values, the engine rpm values, and the accelerator position to determine whether the accelerator increase or the accelerator decrease function should be initiated so that the cruise control speed matches the speed limit zone.
