The present disclosure includes a system, method, and device related to data collection and communication related to after-market and external vehicle systems, such as towing systems, cargo carrying systems, trailer breakaway systems, brake systems, braking control systems, and the like. Data is sensed, processed, shared, and further leveraged throughout the discrete components of the system, and possibly via internet and other communications' links, to effect various beneficial actions with minimal driver/user interaction or intervention. In the same manner, data from the system may be used for diagnostic reasons, safety controls, and other purposes.

An agricultural machine includes one or more tires, a detector to detect a low pressure state in which a pressure of one of the tires is lower than a reference range or a high pressure state in which the tire pressure is higher than the reference range, and a controller to control an operation of at least one of the agricultural machine and an additional agricultural machine to be linked to the agricultural machine. One of the agricultural machine and the additional agricultural machine is a work vehicle that is capable of self-driving, and the other one is an implement to be linked to the work vehicle. The controller causes, in response to detection of the low or high pressure state, at least one of the agricultural machines to perform a specific operation that is different from an operation to be performed when the pressure is in the reference range.

A tire system includes a tire-side device and a vehicle-body-side system. The tire-side device may be attached to a tire included in a vehicle. The vehicle-body-side system may be attached to a body of the vehicle. The tire-side device may output a detection signal corresponding to each of a plurality of types of detection targets. The tire-side device may perform processing of the detection signal and generate the data related to the detection target. The tire-side device may perform bidirectional communication with the vehicle-body-side system and transmit the data to the vehicle-body-side system. The vehicle-body-side system may perform bidirectional communication with the tire-side device and receive the data. The vehicle-body-side system may acquire the detection result for the detection target based on the data.

Method for updating at least one vehicle model parameter and at least one tire parameter in at least one chassis control unit of a vehicle, based on tire sensor information collected by a tire sensor placed on a tire. The method includes the steps of: collecting tire sensor information; updating the at least one vehicle model parameter based on updating at least one tire parameter, updating one tire parameter being based on the tire sensor information.

A method and a corresponding electronic control system for ascertaining a distance traveled by a vehicle predicts with a Kalman filter a distance traveled by the vehicle using a change in angle of rotation of at least one right wheel and/or at least one left wheel of the vehicle for a specific period of time while the vehicle is traveling and an ascertained radius of the right wheel and/or ascertained circumference of the right wheel of the vehicle and/or an ascertained radius of the left wheel and/or ascertained circumference of the left wheel of the vehicle; and corrects the predicted traveled distance by a Kalman filter correction to ascertain the distance traveled by the vehicle using the predicted traveled distance and a local distance between at least two absolute positions of the vehicle recorded within the specific period of time with a time interval while the vehicle is traveling.

A control unit for a vehicle is designed to detect movement sensor data with regard to a movement of at least one component of the vehicle. The movement is or has been effected by a roadway driven upon by the vehicle. In addition, the control unit is designed to detect a lane boundary of the roadway on the basis of movement sensor data and, in reaction thereto, to cause a functional reaction of the vehicle.

Disclosed herein is a vehicle control system capable of improving driving stability and providing safe fun driving to a driver by varying and controlling a regenerative braking torque generated by a motor during coasting. The vehicle control system according to an embodiment of the disclosure includes: a motor configured to provide a driving force to a wheel; a wheel sensor configured to detect a rotational speed of the wheel; and a controller configured to control the motor to generate a first regenerative braking torque during coasting, and to control the motor to generate a second regenerative braking torque lower than the first regenerative braking torque when a wheel slip of the wheel is detected based on an output of the wheel sensor.

A vehicle control device including a tire-side device and a vehicle-side device is provided. The tire-side device includes a vibration detection unit that outputs a detection signal corresponding to a magnitude of vibration of a tire, a signal processing unit that generates data representing a friction coefficient between the tire and a road surface by processing the detection signal, and a transmitter that transmits the data. The vehicle-side device includes a receiver that receives the data and a travel control unit that estimates the friction coefficient based on the data, acquires a braking distance of the vehicle based on the friction coefficient, and controls acceleration and deceleration of the vehicle based on the braking distance.

Systems and methods for detecting a failure of a wheel speed sensor. One example system includes an encoder and an electronic processor. The electronic processor is configured to receive, from the wheel speed sensor, a wheel speed, receive, from the encoder, a signal, and determine, based on the signal from the encoder, a positional change of an electric motor shaft of the electric motor. The electronic processor is configured to determine, based on the wheel speed and the positional change of the electric motor, whether the wheel speed sensor is faulty.
