Title: Controller for rear wheel steering device
Inventor: FURUUMI HIROSHI
IPC: B62D6/00
Filed: 2000-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a controller for a rear wheel steering device capable of excluding effects of mechanical backlash. SOLUTION: After detecting a point P1 in figure (a), rotation of an electric motor is continued as shown in figure (b) until a driving angle sensor detects a point P2 equivalent to a minimum value. When the driving angle sensor detects the point P2 (when it detects a voltage E5), motor control is practiced of stopping the electric motor and then starting the electric motor in a rotating direction switched state as shown in the figure (b). Since an appearing position of the minimum value P2 matches a true neutral position regardless of an existence of the mechanical backlash, very favorable motor control can be performed by driving the electric motor until an output of the driving angle sensor reaches the minimum value P2 during neutral return control.
