COMPUTE SYSTEM WITH CONTROLLER AREA NETWORK ERROR PROTECTION MECHANISM AND METHOD OF OPERATION THEREOF
A method of operation of a compute system comprising: operating a controller area network with a first node including a first error counter and a second node including a second error counter; transmitting a message from the first node to the second node over the controller area network; detecting an error by the first node or the second node; incrementing the first error counter or the second error counter based on whichever the first node or the second node that detected the error; and shutting off an on-board diagnostic port when the first error counter or the second error counter reaches a shut-off threshold.
Systems and method for exhaust warm-up strategy
Methods and systems are provided for controlling a vehicle engine to adjust exhaust warm-up strategy based on a vehicle network information. In one example, in response to an expected decrease in temperature of a catalyst of a vehicle below a threshold and an estimated duration thereof based on communications external from the vehicle, a method may include delaying catalyst heating actions, when the catalyst heating actions are determined to be unable to heat up the catalyst to threshold temperatures. However, the catalyst heating actions may be enabled when the catalyst heating actions are determined to be able to achieve the threshold temperature within the duration.
VEHICLE COLLISION AVOIDANCE METHOD AND SYSTEM
In order to avoid a collision between a vehicle (1) and other traffic, an on-board system (100) of the vehicle (1) scans for target entities (2) in at least one lane (5, 6) to a side of the vehicle (1) and determines position and state of motion of detected target entities (2). From a state of the vehicle (1) an intention of a driver of the vehicle (1) to move the vehicle (1) into one of the at least one lanes (5, 6) scanned is inferred. If the on-board system (100) detects a risk of collision between a target entity (2) and the vehicle (1), then, if such an intention of the driver is found, the motion of the vehicle (1) is impeded by the system (100), applying brakes (200) of the vehicle (1) and/or reducing a driving torque of the vehicle (1). A speed of the vehicle (1) is monitored and a motion of the vehicle (1) is not impeded if the speed of the vehicle (1) is above a pre-defined threshold.
High-performance road vehicle with automatic configuration acquisition and corresponding control method
