SISTEMA DE CONTROLE AUTOMATICO DE VELOCIDADE PARA VEICULOS PESADOS
An automatic speed control for a heavy vehicle including a system control unit (10) which regulates communication between a compressed air source (18) and an air actuated throttle (19); the system control unit (10) generates control signals over lines (15,17) which are a function of a speed error si...

| description | An automatic speed control for a heavy vehicle including a system control unit (10) which regulates communication between a compressed air source (18) and an air actuated throttle (19); the system control unit (10) generates control signals over lines (15,17) which are a function of a speed error signal and the position of the air actuated throttle (19) to regulate the compressed air source (18); the speed error signal is calculated as the difference between a commanded speed signal input from a pair of set and resume switches (34,36) and an actual speed signal (AVS); to generate the control signals, the speed error signal and throttle position signal (THL) are operated on inthe system control unit (10) by different lead-lag transfer functions, and these lead-lag terms are thereafter combined with a proportional speed error term to yield the desired control signals; according to the invention the system control unit (10) includes a cruise control means for controlling the vehicle speed to a commanded speed when the vehicle is moving, a throttle control means for controlling the engine speed when the vehicle is stationary and a mode control means for switching control of the system between the cruise control means and the throttle control means. |
