  • Patent number: 10967922
    Abstract: An all-terrain vehicle for civil protection activities includes a vehicle structure with at least one module for transporting persons and/or material, and a plurality of legs bearing respective wheel assemblies or track assemblies. Each leg is pivotably mounted about a first transverse axis. One first end of the leg carries a wheel assembly or a track assembly and a second end is freely mounted pivoting about the first transverse axis on a first support which is carried by the vehicle structure. An electronically-controlled actuator adjusts an angular position of the first support about a first transverse axis. Between the first support and the leg structure two spring-shock absorber assemblies are interposed, which extend along the leg.

  • Patent number: 9809077
    Abstract: A method for operating a shock-absorber system with shock-absorber devices, in particular switching shock-absorber devices, wherein discretely selectable shock-absorber characteristic curves are provided. The method determines a driving behavior of the driver and/or of the motor vehicle on the basis of one or more driving state data items and/or one or more operating variables and, in automatic mode, automatically sets a shock-absorbing behavior of the shock-absorber system by selecting one of the selectable shock-absorber characteristic curves of the shock-absorber devices as a function of the determined driving behavior.

  • Patent number: 9738321
    Abstract: An arrangement and method are provided for enabling rotation movement between a tandem or caterpillar axle and a body of a vehicle. This type of vehicle includes at least one body part that is provided with a tandem or caterpillar axle. At least one body part includes a main body and an auxiliary body connected to it to rotate around the longitudinal axis of the vehicle or an essentially parallel axis thereto. The tandem or caterpillar axle is connected substantially rigidly to the main body, and the body part has at least one actuator for controlling the rotation movement between the main body and auxiliary body. In this way, changes in the position and motion status of the auxiliary body, especially in relation to the rotation around the longitudinal axis of the vehicle, are arranged to cause in the actuator a pushing or pulling motion that steers the auxiliary body to a rotation movement for the purpose of arranging the auxiliary body to a substantially horizontal position.

  • Patent number: 9644415
    Abstract: Described herein is a method for controlling a motor-powered hatch arrangement of a motor vehicle, wherein the hatch arrangement has an upwardly deflectable hatch, in particular an upwardly pivotable hatch, a drive arrangement which is assigned to the hatch and a control arrangement which is assigned to the drive arrangement, wherein the motor-powered deflection of the hatch in the opening direction is limited to a maximum hatch deflection by means of a control arrangement. It is proposed that the chassis of the motor vehicle can be adjusted vertically as required in order to set different vehicle body levels, and in that the maximum hatch deflection is adapted to a change in the vehicle body level by means of the control arrangement.

  • Patent number: 9598079
    Abstract: The engine control device is applied to a vehicle equipped with a suspension control device for driving stepping motors for changing damping forces of shock absorbers. The suspension control device performs an initializing process for resolving the step-out of the stepping motors by driving the stepping motors when an initialization performing condition is satisfied. The engine control device continues the engine operation when a signal for inhibiting the automatic stop of the operation of the engine is sent to the engine control device and the engine control device judges that no malfunction occurs in the suspension control device even if the engine stop condition is satisfied. The engine control device automatically stops the operation of the engine when the engine stop condition is satisfied and the engine control device judges that a malfunction occurs in the suspension control device even if the signal is sent to the engine control device.

  • Patent number: 9428022
    Abstract: The present invention provides a control system operable to raise and lower the height of a vehicle based in part on the response characteristics of the vehicle's suspension and vehicle loading. The control system may develop a vehicle suspension system response by mapping a correlation between changes in air pressure of air springs in the vehicle's suspension and a test valve-open-time. During operation, the control system may predict a valve-open-time in response to a command relating to a target air pressure for the air springs, and then inflate or deflate one or more of the air springs for a duration substantially equal to the predicted valve-open-time. This process may be iterated until the control system achieves, within an acceptable degree of error, the target air pressure for the one or more air springs.
