Roll stability for a vehicle is provided using motor torque adjustments to wheels of the vehicle. When a vehicle state indicative of an undesirable roll stability level is detected, a roll stability mode is activated. In response to activating the roll stability mode, motor torque to at least one wheel of the vehicle is adjusted independently of motor torque to other wheels of the vehicle.

A vehicle control apparatus is disclosed. The vehicle control apparatus includes a distance sensor configured to sense a distance from a speed bump, a speed sensor configured to sense a speed of a vehicle, a vehicle driver configured to control an operation of a brake or an operation of an accelerator, and a processor configured to provide an input parameter comprising a speed and a weight of the vehicle to a prediction model and control the vehicle driver so that the brake is operated at a braking intensity outputted from the prediction model when the vehicle enters the speed bump on the basis of the distance from the speed bump.

A non-transitory computer readable medium having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to receive road quality data from at least one vehicle in a fleet of vehicles and determine a route for the at least one vehicle in the fleet of vehicles. The road quality data may be gathered by at least one sensor configured to detect autonomous vehicle movements and orientation. The route may avoid a segment of road that is associated with poor road quality data.

In some examples, a controller determines a target condition of usage of a vehicle, and selects a parameter set from among a plurality of parameter sets based on the determined target condition of usage of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller transmits, to the vehicle, the selected parameter set to control a setting of the one or more adjustable elements of the vehicle.

Methods, apparatus, and articles of manufacture are disclosed for limiting a load applied to a rotatable shaft joint. An example apparatus comprises a comparator to, based on at least one of an angle of a rotatable shaft joint or a torque applied to the joint, determine whether at least one of the torque or the angle exceeds a threshold, and a limiter to limit at least one of the angle or the torque when at least one of the torque or the angle exceeds the threshold.

A method for operating an onboard network of a hybrid motor vehicle. The onboard network is connected to an energy storage unit, especially a battery; an electric motor of a hybrid drive train, which also has an internal combustion engine; and actuators of an electromechanical chassis system that can be operated as generators. At least one reserve capacity of the energy storage unit is kept open for the supplying of electrical energy generated by at least one portion of the actuators to the onboard network. The reserve capacity being held open is dynamically adapted as a function of at least one item of driver style information describing the driving style of the driver of the hybrid motor vehicle and/or at least one item of situation information describing the current and/or future operation of the hybrid motor vehicle.

A method to control, while driving along a curve, a road vehicle with a variable stiffness and with rear steering wheels. The method comprises the steps of: determining an actual attitude angle of the road vehicle; establishing a desired attitude angle; determining an actual yaw rate of the road vehicle; establishing a desired yaw rate; and changing, in a simultaneous and coordinated manner, the steering angle of the rear wheels and the distribution of the stiffness of the connection of the four wheels to the frame depending on a difference between the actual attitude angle and the desired attitude angle and depending on a difference between the actual yaw rate and the desired yaw rate.

A vehicle height adjustment control apparatus is provided for compensating for vehicle pulls including a recognition device that recognizes that a vehicle is driven straight, a determination device that determines whether the vehicle pulls of the vehicle occur, in response to recognizing that the vehicle is driven straight, and a controller that generates a warning message and calculates compensation height control information of the vehicle in response to determining that the vehicle pulls occur.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A method and apparatus that address motion sickness are provided. The method includes receiving rider profile information, trip information, environmental information and vehicle dynamics information, determining a probability that a rider will suffer from motion sickness during a ride based on the rider profile information, the trip information, the environmental information and the vehicle dynamics information, in response to the probability being greater than a predetermined threshold probability corresponding to a rider, performing motion sickness mitigation functions, and in response to the probability being less than the predetermined threshold probability corresponding to the rider, monitoring the rider to detect rider response information indicating whether the rider will suffer from motion sickness during the ride.
