Abstract

Abstract An equipment for detecting the movement of a preceding vehicle and giving warning. When one's own vehicle (hereinafter referred to as "the vehicle") is at a stop, the equipment detects the forward or backward movement of said preceding vehicle and gives warning to the driver of the vehicle. The equipment comprises a distance measuring sensor for measuring the distance between the vehicle and said preceding vehicle when the vehicle is at a stop, a memory device for memorizing a value measured by said distance measuring sensor, a measurement command device for making said distance measuring sensor repeatedly measure the distance between the vehicle and said preceding vehicle, a comparison device for comparing said memorized value measured by said distance measuring sensor with values subsequently measured by said distance measuring sensor, and a warning device for giving warning when any of said values subsequently measured is different from said memorized value.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 114 words
An equipment for detecting the movement of a preceding vehicle and giving warning, said equipment comprising a distance measuring sensor for measuring the distance between the vehicle and said preceding vehicle when the vehicle is at a stop, a memory means for memorizing a value measured by said distance measuring sensor, a measurement command means for making said distance measuring sensor repeatedly measure the distance between the vehicle and said preceding vehicle, a comparison means for comparing said memorized value measured by said distance measuring sensor with values subsequently measured by said distance measuring sensor, and warning means for giving warning when any of said values subsequently measured is different from said memorized value.
Claim 2
Dependent Claim 114 words
An equipment for detecting the movement of a preceding vehicle and giving warning, said equipment comprising a distance measuring sensor for measuring the distance between the vehicle and said preceding vehicle when the vehicle is at a stop, a memory means for memorizing a value measured by said distance measuring sensor, a measurement command means for making said distance measuring sensor repeatedly measure the distance between the vehicle and said preceding vehicle, a comparison means for comparing said memorized value measured by said distance measuring sensor with values subsequently measured by said distance measuring sensor, and warning means for giving warning when any of said values subsequently measured is different from said memorized value.
Claim 3
Dependent Claim 30 words
An equipment as claimed in claim 1 wherein said equipment has a manual switch as a starting means thereof, and said equipment is started when the manual switch is manipulated.
Claim 4
Dependent Claim 58 words
An equipment as claimed in claim 1 wherein said equipment has, as a starting means thereof, a vehicle speed sensor adapted to detect a zero speed of the vehicle when the vehicle is at a stop and give a zero speed detection signal, said equipment being started when said vehicle speed sensor gives a zero speed detection signal.
Claim 5
Dependent Claim 80 words
An equipment as claimed in claim 1 wherein said equipment has, as starting means thereof, a brake pedal pressing detection means adapted to give a brake pedal pressing detection signal when the brake pedal is pressed, and said manual switch or said vehicle speed sensor, said equipment being started when said brake pedal pressing detection means gives a brake pedal pressing detection signal and said manual switch is manipulated or said vehicle speed sensor gives a zero speed detection signal.
