The configuration includes: a motor for driving a driving wheel (rear wheel) provided to a body; a slip ratio calculating section for calculating a slip ratio while the lawn mower is traveling; a friction coefficient calculating section for calculating a friction coefficient of a ground on which the lawn mower is traveling; a determination section for determining whether the ground on which the lawn mower is traveling is a lawn based on a relationship between the slip ratio and the friction coefficient and a drive controlling section for controlling the motor based on a determination result from the determination section. This configuration allows suitable driving operability for both of a case where the ground on which a lawn mowers traveling is a lawn and a case where the ground is other than a lawn.

The system includes an oscillating chassis (10) suitable for being linked to an axle (6) of a vehicle (1); two cylinders (11, 12), referred to as compensation cylinders, linking the oscillating chassis (10) to the main chassis (5) of the vehicle; a proportional distributor or valve (13) to which the compensation cylinders (11, 12) are connected; an axle tilt detector (14) detecting tilt of the axle (6) resulting in the wheel (2) of the vehicle (I) opposite the arm (3) being raised; and a computer (15) connected to this tilt detector (14) and to piloted actuation device (30) for actuating the valve-slide of the proportional distributor (13); in the event of the axle (6) tilting in a manner that tends to raise the wheel (2) situated on the side opposite the arm (3), the computer (15) controls these actuation device (30) in such a way as to control the valve-slide of the proportional valve (13). The vehicle (1) is equipped with the stabilization system.

Known vehicles, e.g. used for the sport of golf, which are configured combined for riding along and to be pushed with motorized support, exclusively comprise a steerable, rigid frame, causing the vehicle when positioned on the side of a slope to tilt parallel to the slope plane, consequently resulting in a disadvantageous, safety-relevant tilting moment. For improved driving safety, it should be possible to tilt the vehicle sideways. The vehicle according to the invention can be used in at least two operating modes. In the ride-along mode, at least a second and/or third vehicle component can be moved by the operator or an automatic, thus causing the vehicle to tilt sideways. This enables a carving effect and the tilt compensation as well as a straight-ahead drive at least in side slopes and inclines. In the push mode, the male/female user walks behind or beside the vehicle, and at least two vehicle components and/or parts thereof are located in a position, relative to each other, different as compared to the position in the ride-along mode. The versatile embodiment variations make it possible to use it as a golf vehicle, as well as a recreational-/, shopping-/, transport-/, industrial-/, construction site vehicle, and as a vehicle for the transport of senior and handicapped persons, for exploration and military purposes, for mowing, as an agricultural vehicle, as gardening appliance and as a child carrier.

Herein a self-propelled robotic lawnmower (1) Is disclosed comprising a lawnmower chassis (3.1, 3.2) and wheels (5.1-5.4) arranged at the lawnmower chassis (3.1, 3.2). The wheels (5.1-5.4) are arranged to support the lawnmower chassis (3.1, 3.2) during operation of the lawnmower (1). The wheels (5.1-5.4) comprise at least a first wheel (5,1) and a second wheel (S.2), wherein the first and second wheels (5.1, S.2) are arranged at opposite lateral sides (6.1, 6.2) of the lawnmower chassis (3.1, 3.2). At least the first and second wheels (5.1, 5.2) are arranged at the lawnmower chassis (3.1, 3.2) with a negative camber angle (a).
