Title: Safety brake light control - uses impulse generator coupled to brake light with frequency determined by retardation
Inventor: HOERINGKLEE MANFRED ING GRAD
IPC: G01P15/16
Filed: 1975-02-19
Abstract: The retardation of the vehicle is monitored and is used to control the frequency of an impulse generator coupled to the brake lights. The following vehicles can thus judge the amount of braking accurately. The retardation signal is derived in one of several simple ways translated into a signal level and stored in a reference capacitor. The stored value is then compared with a second value, after a set time interval, with the difference in levels proportional to the retardation. The brake pressure can be directly used to modulate the frequency of the impulse generator, as can the displacement of an inertial mass.
