Tilting vehicle and control system thereof
First Claim
1. Vehicle comprising at least one tiltable steering wheel (3), at least two wheels (3, 4) other than the steering wheel (3), control means (11) suitable for being operated by a driver to steer said steering wheel (3), a frame (2) supported by said wheels (3, 4) and tiltable together with said at least one steering wheel (3) with respect to a ground surface when the vehicle turns and first actuating means (23) to control a tilting position of said frame (2) and of said at least one steering wheel (3), characterized by comprising a decoupling device (14) to decouple said control means (11) from said steering wheel (3), a control unit (25) configured so that said first actuating means (23) tilt said frame (2) and said at least one tiltable steering wheel (3) when said control means (11) are operated by the driver, second actuating means (15) connected to said control unit (25) to control the steering angle of said steering wheel (3) and a speed sensor (24) connected to said control unit (25) to measure a speed of the vehicle, and in that said control unit (25) is configured to activate said second actuating means (15) depending on the speed measured by said speed sensor (24), wherein said control unit (25) is configured to activate said second actuating means (15) with a time delay with respect to said first actuating means (23).

Abstract
A vehicle comprises at least one steering wheel, at least two other wheels, control means suitable for being operated by a driver to steer the steering wheel, a frame supported by said wheels and tiltable with respect to the ground when the vehicle steers and first actuating means to control the tilting position of said frame. In particular, vehicle comprises a decoupling device to decouple the angular position of control means to the angular position of steering wheel and a control unit configured to activate first actuating means when control means are operated by the driver before said steering wheel substantially changes its angular position at least when said vehicle turns running above a given speed threshold.

- 13. Control method for a vehicle comprising at least one steering wheel (3), at least two wheels (3, 4) other than the steering wheel (3), control means (11) suitable for being directly operated by a driver to steer said steering wheel (3), a frame (2) supported by said wheels (3, 4) and tiltable with respect to a ground when the vehicle steers, first actuating means (23) to control an angular position of said frame (2), a decoupling device (14) decoupling an angular position of said control means (11) to an angular position of said steering wheel (3), second actuating means (15) connected to said control unit (25) to control a steering angle of said steering wheel (3) and a speed sensor (24) connected to said control unit (25) to measure a speed of the vehicle, said method comprising a phase of enabling said actuating means (23) when said control means (11) are operated by a driver and a phase of activating said second actuating means (15) depending on a speed measured by said speed sensor (24), wherein said phase of activating said second actuating means (15) is such that said control unit (25) activates said second actuating means (15) at a given time delay with respect to said phase of activating said first actuating means (23).
