Method and apparatus are disclosed for energy-consumption detection of vehicles in an off state. An example vehicle includes a controller area network (CAN) including CAN buses, a gateway module, and electronic control units (ECUs) that are each connected to one of the CAN buses. Upon activating while the vehicle is in an off state, a first of the ECUs sends a message via a corresponding one of the CAN buses to activate the gateway module. The message includes activation data and the gateway module stores the activation data.

An electronic control device includes: an acquisition unit that acquires state information indicating at least one of a state of a movable body and a state of an external environment in which the movable body is moving, and a control instruction indicating at least one of a steering control instruction for steering the movable body and an acceleration control instruction for adjusting acceleration of the movable body; and a determining unit that determines whether the control instruction is a false control instruction based on the at least one state indicated by the state information acquired and control indicated by the control instruction acquired.

Described herein is a system and method for preemptive chassis control intervention for an autonomous vehicle having a mechanical system and a chassis controller. The chassis controller is configured to output a consumption signal that represents a percentage of an activation threshold consumed by an operation monitored by the chassis controller, wherein the chassis controller is activated to manipulate the mechanical system when the activation threshold is reached. A computing system of the autonomous vehicle receives the consumption signal output by the chassis controller to determine a path plan for the autonomous vehicle based upon the percentage of the activation threshold consumed by the operation monitored by the chassis controller. The computing system further controls the mechanical system to execute the path plan to preempt activation of the chassis controller.

Methods, apparatuses, and computer-readable media are described. In one example, a method of controlling a vehicle comprises: receiving, using one or more sensors, a first set of measurements of a set of physical attributes of the vehicle in a motion; determining, based on a motion data model that defines a set of relationships among the set of physical attributes of the vehicle in the motion and based on the first set of measurements, a set of expected measurements of the set of physical attributes; determining whether to use an entirety of the first set of measurements to control an operation of the vehicle based on comparing the first set of measurements and the set of expected measurements; and responsive to determining not to use the entirety of the first set of measurements, controlling the operation of the vehicle based on a second set of measurements.

The present disclosure relates to electronic system and methods for switching a driving mode of a vehicle. The electronic system may include at least one sensor configured to connect to a driving system of a vehicle; at least one gateway module connected to the at least one sensor through a controller area network; and processing circuits connected to the at least one gateway module. During operation, the processing circuits may receive at least one trigger signal from the at least one sensor; determine that the at least one trigger signal meets a predetermined condition; and send at least one switching signal to the gateway module to switch the vehicle from a current driving mode to a target driving mode.

A motor system includes a motor, a first electronic control unit, a second electronic control unit, a first communication line, and a second communication line. The first electronic control unit transmits first data of the control command to the second electronic control unit via the first communication line when an abnormality has not occurred in the first communication line. The second electronic control unit controls the motor based on the first data after the first data has been received from the first electronic control unit. The first electronic control unit generates second data and to transmit the second data to the second electronic control unit via the second communication line when an abnormality has occurred in the first communication line. The second electronic control unit controls the motor based on the second data after the second data has been received from the first electronic control unit.

A control unit for a vehicle, having an interface for the exchange of data with a sensor, an actuator, and/or a processing unit, including a data memory, in which a first list with multiple first reference numbers (port) is stored. At least one datum of a sensor or an actuator is allocated to a first reference number, and a second list with second reference numbers is stored in the data memory. At least one parameter of a data transmission is stored for each second reference number, a first reference number being allocated via a modifiable allocation to a second reference number, and the control unit being developed to receive and/or transmit the data of a first reference number in accordance with the parameter of the data transmission of the second reference number.

A controller may include one or more processors configured to control an automotive operating function representing an operation of an actuator of an automobile; receive a first message in accordance with an automotive fieldbus communication protocol via a fieldbus communication network, wherein the first message comprises contextual information associated with the automobile; determine whether a relation between the contextual information and a status of the automotive operating function fulfills a predefined criterion; generate a second message in accordance with the automotive fieldbus communication protocol, wherein the second message comprises information representing a result of the determination.

A method for controlling a suspension component of a vehicle, in which a control unit of the suspension component continuously generates a plurality of control requirements according to a generation clock frequency, each requirement comprising a control value, for an actuator of the suspension component. A bus system of the vehicle continuously transmits to the actuator the control requirements generated by the control unit according to a transmission clock frequency. The actuator calculates a target output value for the suspension component from the control value of each transmitted control requirement and an actual output value of the suspension component, and adjusts the suspension component corresponding to the calculated target output value.

There is described a controller area network (CAN) message scanner for a winter service vehicle. The CAN message scanner generally has a housing; a controller inside said housing; and a CAN bus link having a proximal end connected to said controller and a distal end connected to a diagnostic port of an engine control unit (ECU) of said winter service vehicle; said controller performing, while said winter service vehicle has a given speed, receiving a CAN message from said ECU vehicle via said CAN bus link, said CAN message having vehicle data fields located at corresponding addresses of said CAN message; retrieving a vehicle data field having a value matching a speed value indicative of said given speed of said winter service vehicle; and generating a signal indicating an address corresponding to said retrieved vehicle data field.
