An air management system for a vehicle having a first pneumatic circuit and a second pneumatic circuit, in which the first and second pneumatic circuits are pneumatically connected in a neutral position via a cross-flow mechanism. The first pneumatic circuit includes a first leveling valve configured to adjust independently the height of a first side of the vehicle. The second pneumatic circuit includes a second leveling valve configured to adjust independently the height of a second side of the vehicle. The first and second leveling valves are configured to establish pneumatic communication between the first and second pneumatic circuits when the first leveling valve is not independently adjusting the height of the first side of the vehicle and the second leveling valve is not independently adjusting the height of the second side of the vehicle.

An adjustment system and method for adjusting a chassis property of a motor vehicle wherein an understeering sensitivity of the motor vehicle is increased upon detecting that a trailer has been coupled to the motor vehicle. A detection unit operates to detect when a trailer is attached or coupled to the motor vehicle.

A method for operating a motor vehicle with a chassis arrangement having at least two vibration dampers. A body control is carried out at least partially with the vibration dampers. The chassis arrangement further has at least one stabilizer. During transverse accelerations below a threshold acceleration the stabilizer contributes to the body control less than the vibration dampers and contributes more than the vibration dampers from the threshold acceleration upward.

Motor vehicle comprising a drive system arranged in a compartment at the front of a vehicle, a cradle (2) comprising a platform (4) fastened in this compartment in the region of a floor of the vehicle, an anti-roll bar (10) fastened in the vertical direction above the platform (4), and an impact device (30) fastened to a front edge (20) of the platform (4), behind an impact block fastened to a powertrain of this vehicle, in order, in the event of a recoil of this powertrain, to allow the impact block to bear on the impact device (30), which deforms, the impact device (30) comprising an upper part projecting above the platform (4), which, in the event of a large deformation, bears on the anti-roll bar (10).

An automatic tilting vehicle is provided that includes left and right front wheels supported by knuckles, a steerable rear wheel, a vehicle tilting device, and a control unit. The vehicle tilting device includes a swing member, a tilt actuator for swing the swing member, and a pair of tie rods pivotally attached to the swing member and the knuckles. The control unit calculates a target lateral acceleration of the vehicle, estimates a lateral acceleration of the vehicle caused by the gyro moments of the wheels and calculates a target tilt angle of the vehicle based on a sum of the target lateral acceleration and the lateral acceleration caused by the gyro moments.

Automatic tilting vehicle is provided that includes left and right front wheels supported by knuckles, a rear wheel steered by a steering actuator, a vehicle tilting device, and a control unit. The control unit calculates a target tilt angle of the vehicle and a target steered angle of the rear wheel based on a steering angle and a vehicle speed, controls the vehicle tilting device so that a tilt angle of the vehicle becomes the target tilt angle, and controls the steering actuator so that a steered angle of the rear wheel becomes the target steered angle. When the vehicle is turning and decelerating, a steered angle of the rear wheel is controlled not to be the target steered angle but to zero, and a tilt angle of the vehicle is reduced by a gyro moment of the rear wheel.
