Abstract
An electronic device for selecting and controlling the steering modes of vehicles, in particular industrial vehicles, comprising an electronic control unit (30), which receives two input signals (S3, S4) from two magnetic sensors (34, 36), which are placed onto the pistons (20, 22) of the rear axle and the front axle, respectively, of the vehicle; the sensors (34, 36) are activated when suitable magnetic bands (32, 38) which are provided on the pistons (20, 22) of the steering cylinders (24, 26), pass in front of them and they enable, by means of the control unit (30), an automatism (28) that switches to a prefixed steering mode when the front and rear wheels of the vehicle are aligned.
