Travel control device, travel control system, travel control method, and tire testing device

This travel control device is provided with a controller for controlling travel of a vehicle fitted with tires, using automated driving. The vehicle travels on a course including a testing section for testing the tire. The controller controls travel of the vehicle so that the vehicle travels on the testing section based on a prescribed standard for testing of the tire.

METHOD FOR CONTROLLING OIL PRESSURE IN AN OIL PUMP OF AN INTERNAL COMBUSTION ENGINE SYSTEM

A method for controlling oil pressure in a controllable oil pump of an internal combustion engine system. A vehicle is arranged in communication with a control unit, the method comprising: receiving an indication of an upcoming vehicle operating situation affecting an operation of the ICE system; determining an expected change in the operation of the ICE system for the upcoming vehicle operating situation; determining a current oil pressure of the oil pump; and on the basis of said determined expected change in the operation of the ICE system and the determined current oil pressure of the oil pump, determining a minimum oil pressure for the oil pump for the upcoming vehicle operating situation.

Method of controlling a prime mover of a vehicle, apparatus for controlling a prime mover of a vehicle, and a vehicle comprising such an apparatus

Controlling a prime mover of a first vehicle following a first path is based, at least in part, on a likely speed behaviour of a second vehicle ahead of the first vehicle, which is estimated based on a predicted path of the second vehicle. At least one coasting profile for the first vehicle is estimated for at least part of the first path and/or the predicted path. At least one of the coasting profiles is determined that meets at least one predetermined coasting requirement. The prime mover may be controlled to place the vehicle into a coasting mode based on the determined coasting profile. Alternatively, feedback is provided to a user to put the vehicle into a coasting mode.

Methods and system for stopping an engine

Systems and methods for stopping an engine of a vehicle are described. In one example, the method anticipates when an engine is expected to stop and modifies engine operation so that less fuel is in the engine's intake ports when the engine is stopped so that the fuel may not escape the engine when the engine is restarted.

ADJUST CONTROL STRATEGY BASED ON FAULT EVENTS COMBINED WITH PREDICTIVE DATA

A method for prevention of fault events on vehicles including: acquiring predictive data related to predictive events for a vehicle; processing the predictive data with a vehicle performance model adapted to relate specific predictive events to specific vehicle performance events; and adjusting a control strategy for the vehicle based on an outcome of the processing to at least reduce the risk that a specific vehicle performance event occurs when the vehicle reaches a corresponding specific predictive event.

CONDITION BASED VEHICLE PERFORMANCE MANAGEMENT

A vehicle includes a chassis, a driveline coupled to the chassis, and a control system. The control system is configured to monitor a condition of at least one of the vehicle, an area around the vehicle, or an operator of the vehicle; and control operation of the driveline based on the condition. Controlling the operation of the driveline includes at least one of limiting a speed at which the driveline drives the vehicle or shutting down the driveline and isolating a component of the driveline.

An internal combustion engine system includes an internal combustion engine, a controller, and an increased brake load event communicator. The internal combustion engine includes a first cylinder and a first cylinder deactivation prevention mechanism. The first cylinder is configured to be selectively activated and deactivated. The first cylinder deactivation prevention mechanism is configured to selectively prevent the first cylinder from being deactivated. The controller is communicable with the first cylinder deactivation prevention mechanism. The controller includes an increased brake load event detection module that is configured to selectively control the first cylinder deactivation prevention mechanism to prevent the first cylinder from being deactivated. The increased brake load event communicator is communicable with the controller. The increased brake load event detection module is configured to control the first cylinder deactivation prevention mechanism to prevent the first cylinder from being deactivated based on a communication from the increased brake load event communicator.

Control device for vehicle

A CPU of a control device is configured to perform a specific cylinder fuel cutoff process of causing an internal combustion engine to operate such that supply of fuel to some cylinders out of a plurality of cylinders is stopped and supply of fuel to the other cylinders is maintained and a fastening force decreasing process of decreasing a fastening force of a lockup clutch of a torque converter. The CPU is configured to start the specific cylinder fuel cutoff process in a state in which the fastening force has been decreased through the fastening force decreasing process when the specific cylinder fuel cutoff process is performed in a state in which the internal combustion engine operates with a load.

Fuel selection method and related system for a mobile asset

Embodiments of methods and systems related to operating a mobile asset are provided. In one example, a method for operating a mobile asset includes supplying an engine with a fuel controller a first amount of a first fuel and a second amount of a second fuel and combusting the first fuel and the second fuel at a fuel combustion ratio in at least one cylinder of the engine, the first amount and the second amount being selected based on route information for a route along which the mobile asset is operable to travel and a projected exhaustion of the first fuel that does not precede a projected exhaustion of the second fuel, wherein the mobile asset is unable to operate with the second fuel alone.

Method and system for vehicle stop/start control

Methods and systems are presented for improving performance of a vehicle operating in a cruise control mode where a controller adjusts torque output from a vehicle to maintain vehicle speed within a desired range. The methods and systems include adapting a vehicle dynamics model and a vehicle fuel consumption map that provide input to nonlinear model predictive controller.
