摘要： A vehicle control system and method receive vehicle makeup information from multiple vehicles in a multi-vehicle system. The vehicle makeup information represents one or more characteristics of the vehicles. The vehicle makeup information is received at a controlling vehicle of the vehicles in the multi-vehicle system that controls movement of the multi-vehicle system. The controlling vehicle also receives locations from location-determining devices respectively onboard the vehicles in the multi-vehicle system. The controlling vehicle controls operation of the multi-vehicle system using a combination of the vehicle makeup information received from the vehicles and the locations of the vehicles.

摘要： A control system for a vehicle is provided, which includes a driving force source configured to generate torque for driving drive wheels, a steering angle related value sensor configured to detect a steering angle related value of a steering device, and a controller configured to control the torque to control the vehicle attitude based on the steering angle related value. The controller acquires a current traveling mode defining a response of acceleration or deceleration of the vehicle to an accelerator pedal operation. Based on the steering angle related value, when determined that a turning operation of the steering device in one direction is performed, the controller performs a torque decreasing control to add deceleration to the vehicle. When the acquired traveling mode is a high response traveling mode, the controller increases a reduction amount of the torque in the torque decreasing control more than in a low response traveling mode.

摘要： Technical solutions are described for limiting exposure of components of an emissions control system to rich exhaust conditions. An example an emissions control system includes an oxygen storage component; and a controller that limits exposure of the oxygen storage component to rich exhaust conditions. The limiting includes determining an air-to-fuel equivalence ratio in exhaust gas in response to an engine receiving a request to generate torque, the request including a displacement of a pedal; determining an amount of oxygen in the exhaust gas based on the air-to-fuel equivalence ratio; determining an oxygen level stored by the oxygen storage component; and if the oxygen level is above a predetermined threshold, lowering a torque generation rate of the engine, which specifies amount of torque generated per unit displacement of the pedal.

摘要： A variable gauge train control device comprises an inverter, a location detector, and a torque calculator. The inverter collectively controls torques of main electric motors. The location detector detects an entry into a gauge changeover section. The torque calculator, upon detection by the location detector of the entry into the gauge changeover section, suspends idling control that otherwise restricts the torques of the main electric motors and calculates a first torque pattern for making the inverter operate in accordance with the torques of the main electric motors.

摘要： Methods and systems are provided for diagnosing whether active engine mounts configured to isolate engine vibration from a cabin and chassis of a vehicle are functioning as desired. In one example, a method includes indicating degradation of an active engine mount by inducing degraded combustion events in a preselected engine cylinder, and operating the active engine mount in multiple modes, the indication responsive to an amount of vehicle chassis vibration during each of the modes. By monitoring chassis vibrations as a function of induced degraded combustion events, and further responsive to the active engine mounts being controlled to the multiple modes, it may be indicated as to whether the active engine mounts are functioning as desired.

摘要： Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission, where the transmission is downstream of the engine, and where the electric machine is downstream of the transmission. In one example, while the vehicle is being propelled solely via the electric machine, one or more gears of the transmission may be pre-engaged or selected, to prepare the driveline for an engine start event. In this way, driveline torque disturbance and delays in torque requests may be reduced or avoided upon a request for an engine start event.

摘要： An LPV/MPC engine control system is disclosed that includes an engine control unit connected to multiple sensors. The engine control unit receives, from the sensors, signals indicative of desired engine torque and engine torque output, and determines, from these signals, optimal engine control commands using a piecewise LPV/MPC routine. This routine includes: determining a nonlinear and a linear system model for the engine assembly, minimizing a control cost function in a receding horizon for the linear system model, determining system responses for the nonlinear and linear system models, determining if a norm of an error function between the system responses is smaller than a calibrated threshold, and if the norm is smaller than the predetermined threshold, applying the linearized system model in a next sampling time for a next receding horizon to determine the optimal control command. Once determined, the optimal control command is output to the engine assembly.
