摘要： A control device controls a vehicle including a seat suspension which is provided between a chassis and a seat of the vehicle and restricts vibration and of which each of a spring constant and a damping coefficient is changeable and controllable. The control device detects, as vehicle information, a vehicle speed, an acceleration, a state of acceleration operation by a driver, a state of deceleration operation by the driver, and a state of steering by the driver. The control device determines, based on the vehicle information, whether the driver has driving preference of emphasizing the steering stability performance of the vehicle or driving preference of emphasizing the ride comfort performance of the vehicle, and, according to the determined driving preference, changes an acceleration of the seat by controlling the seat suspension.

摘要： Tire traction is dynamically increased in a vehicle by performing a sequence of steps. First, a center of mass of the body of the vehicle is raised by a predetermined amount above a base level by using an active element of a controllable suspension to generate the positive forces in response to a first signal from a suspension controller. Second, the suspension controller receives a trigger after the center of mass of the body of the vehicle is raised by the predetermined amount above the base level. Third, at least some of the generated positive forces of the active element are removed upon receipt of the trigger in response to a second signal from the suspension controller. The removal of the at least some of the generated positive forces of the active element results in the center of mass of the body of the vehicle dropping back towards the base level and increasing a load on the controllable suspension, thereby dynamically increasing tire traction. The generated positive forces of the active element are removed within a time interval that is sufficient to dynamically increase maximum tire traction by at least ten percent.

摘要： The invention refers to a method of preventing automatic leveling during battery replacement, and a computer-program thereof. The method of preventing automatic leveling during battery replacement, according to invention, operates for an electric vehicle equipped with a first electronic control unit (100) in charge with battery replacement and a second electronic control unit (200) of suspension system, the respective ECUs (100, 200) communicating by means of an internal bus system. The method includes the following steps: (51) Sending an information from the first ECU to the second ECU that the vehicle is prepared to perform a battery replacement; (52) Once said information is received by the second ECU, triggering a leveling forbid flag to the suspension system and deactivating it; (53) Once said deactivation has been performed, setting a feedback signal to inform that battery replacement can commence; (54) during battery replacement, setting said feedback signal to inform that battery replacement is ongoing; (55) Upon completion of battery replacement, informing the second ECU that the battery replacement has been finished successfully, and allowing the activation of suspension.

摘要： Systems, methods, and computer-readable storage media for using multi-stage machine learning algorithms to optimize tire contact patches on a vehicle. Vehicle sensors first collect vehicle information for the vehicle, and input that data into a first machine learning algorithm. The first machine learning algorithm then outputs a lateral dimension, a longitudinal dimension, and a diagonal dimension, which together identify a tire contact patch of at least one tire on the vehicle. The operator of the vehicle provides a human preference for how the vehicle operates, and a second machine learning algorithm is executed. The second machine learning algorithm inputs can include the plurality of vehicle information, the first machine learning algorithm outputs, and the human preference, and the second machine learning algorithm outputs can include a desired tire pressure of the at least one tire and an air suspension adjustment for the normal load of the vehicle.

摘要： A method of controlling a vehicle may include determining a proximity to a stuck condition based on measured vehicle motion parameters and a wheel speed measured by a wheel speed sensor associated with one or more wheels of the vehicle. The method may further include generating a notification to a driver of the vehicle in response to the proximity to the stuck condition indicating that the vehicle is either in a stuck condition or a nearly stuck condition, and responsive to driver selection of an unstuck mode, executing an unstuck algorithm to automatically control operation of the vehicle to achieve a free condition.
