Claim 1
Independent Claim
289 words
A system for controlling the speed of a vehicle having an accelerator operated by an operator and a transmission, said system comprising: means for producing a speed signal corresponding to the speed of said vehicle, a memory for inputting, storing and outputting a value corresponding to a selected speed of said vehicle, a comparator for comparing the output of said memory and said speed signal and for providing a corresponding output signal when the speed signal is less than said output of said memory, an actuator, linked to said accelerator, for depressing said accelerator for increasing the speed of said vehicle in response to an input signal to said actuator, shift means for shifting said transmission from a higher gear to a lower gear in response to an input signal thereto, and for shifting back to said high gear after said input thereto ceases, increase set switch means for changing said value stored in said memory, in correspondence to the vehicle speed during the operation of the increase means, and for providing said input signal to said shift means, and an OR circuit having as inputs the signals corresponding to said output signal of said comparator and to said input of said shift means, and having an output that provides said input to said actuator, wherein, (1) upon operation of said increase set switch means, the speed of said vehicle tends to increase, (2) upon the release of said increase set switch means, a value is stored in said memory corresponding to a value of the vehicle speed during the operation of said increase set switch means, and (3) after said release of said increase set switch means, said actuator is controlled according to the output of said comparator.
Claim 2
Independent Claim
289 words
A system for controlling the speed of a vehicle having an accelerator operated by an operator and a transmission, said system comprising: means for producing a speed signal corresponding to the speed of said vehicle, a memory for inputting, storing and outputting a value corresponding to a selected speed of said vehicle, a comparator for comparing the output of said memory and said speed signal and for providing a corresponding output signal when the speed signal is less than said output of said memory, an actuator, linked to said accelerator, for depressing said accelerator for increasing the speed of said vehicle in response to an input signal to said actuator, shift means for shifting said transmission from a higher gear to a lower gear in response to an input signal thereto, and for shifting back to said high gear after said input thereto ceases, increase set switch means for changing said value stored in said memory, in correspondence to the vehicle speed during the operation of the increase means, and for providing said input signal to said shift means, and an OR circuit having as inputs the signals corresponding to said output signal of said comparator and to said input of said shift means, and having an output that provides said input to said actuator, wherein, (1) upon operation of said increase set switch means, the speed of said vehicle tends to increase, (2) upon the release of said increase set switch means, a value is stored in said memory corresponding to a value of the vehicle speed during the operation of said increase set switch means, and (3) after said release of said increase set switch means, said actuator is controlled according to the output of said comparator.
Claim 3
Dependent Claim
30 words
The system of claim 1, said actuator being of the negative-pressure type wherein said depressing of said accelerator is enhanced by said shifting of said transmission to said lower gear.
Claim 4
Dependent Claim
12 words
The system of claim 1, said actuator being of the motor type.
Claim 5
Dependent Claim
34 words
The system of claim 1, 2 or 3, wherein said value stored in said memory at said release of said increase set switch means represents the vehicle speed at the time of the release.
