Abstract
Abstract A device for the control of the traveling speed of a motor vehicle with a regulating unit actuatable by the vehicle driver, particularly a gas pedal, and means for transmission of the movement of the same to an element, particularly the throttle valve, which influences the fuel-air mixture. An electrical controller is provided, the desired value input of which is applied with the output signal of a first electrical position indicator, the latter being coupled with the regulating unit and the actual value input of which is applied with the output signal of a second electrical position indicator, the latter being coupled with the setting member or positioning actuator of an electrical setting or adjusting device, the actuator standing in connection with the element which influences the air-fuel mixture. Measures are provided which compensate for abnormal speed conditions of the device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
A device for the control of the traveling speed of a motor vehicle with a regulating unit actuatable by the vehicle driver, particularly a gas pedal, and means for transmission of the movement of the same to an element, particularly the throttle valve, which influences the fuel-air mixture, comprising a regulating unit, a first electrical position encoder being coupled with said regulating unit, said first position encoder having an output with an output signal, means for influencing the air-fuel mixture of the vehicle, an electrical adjusting device including a positioning actuator, the latter being connected with said means, a second electrical position encoder being coupled with said positioning actuator, said second electrical position encoder having an output with an output signal, an electrical controller including said electrical adjusting device and having a desired value input connected with the output of said first electrical position encoder and having an actual value input connected with the output of said second electrical position encoder, and wherein the vehicle includes an ignition circuit, the device further comprising means for interrupting the ignition circuit of the motor vehicle upon a deviation of the output signal of said second electrical position encoder from the output signal of said first electrical position encoder by a certain predetermined amount.
Claim 2
Independent Claim
211 words
A device for the control of the traveling speed of a motor vehicle with a regulating unit actuatable by the vehicle driver, particularly a gas pedal, and means for transmission of the movement of the same to an element, particularly the throttle valve, which influences the fuel-air mixture, comprising a regulating unit, a first electrical position encoder being coupled with said regulating unit, said first position encoder having an output with an output signal, means for influencing the air-fuel mixture of the vehicle, an electrical adjusting device including a positioning actuator, the latter being connected with said means, a second electrical position encoder being coupled with said positioning actuator, said second electrical position encoder having an output with an output signal, an electrical controller including said electrical adjusting device and having a desired value input connected with the output of said first electrical position encoder and having an actual value input connected with the output of said second electrical position encoder, and wherein the vehicle includes an ignition circuit, the device further comprising means for interrupting the ignition circuit of the motor vehicle upon a deviation of the output signal of said second electrical position encoder from the output signal of said first electrical position encoder by a certain predetermined amount.
Claim 3
Dependent Claim
34 words
The device according to claim 1, wherein said interrupting means includes an optical and/or acoustical warning device, and means for operatively switching said warning device timewise prior to the interruption of the ignition circuit.
Claim 4
Dependent Claim
19 words
The device according to claim 1, further comprising a manually operable switch means for inoperatively switching said interrupting means.
Claim 5
Dependent Claim
34 words

Claim 6
Independent Claim
129 words
A device for the control of the traveling speed of a motor vehicle with a regulating unit actuatable by the vehicle driver and including a throttle valve comprising: a feedback loop responsive to an actuation by the driver for positioning the throttle valve, said loop including a motorized drive for moving said vehicle, an encoder for sensing the position of said valve, and a comparator for comparing a signal of said encoder with a signal from said driver, and an alarm circuit comprising a comparator coupled to said encoder and responsive to said signal of said driver, a timer, and an alarm responsive to said timer and said comparator for signaling a failure of said throttle valve to return to a position directed by said signal of said driver.
Claim 7
Independent Claim
129 words
A device for the control of the traveling speed of a motor vehicle with a regulating unit actuatable by the vehicle driver and including a throttle valve comprising: a feedback loop responsive to an actuation by the driver for positioning the throttle valve, said loop including a motorized drive for moving said vehicle, an encoder for sensing the position of said valve, and a comparator for comparing a signal of said encoder with a signal from said driver, and an alarm circuit comprising a comparator coupled to said encoder and responsive to said signal of said driver, a timer, and an alarm responsive to said timer and said comparator for signaling a failure of said throttle valve to return to a position directed by said signal of said driver.
