A control device for a vehicle includes an upper limit value setting unit configured to set an upper limit value of an acceleration or deceleration of the vehicle, and a vehicle controller configured to control the vehicle such that the acceleration or deceleration does not exceed the upper limit value. The upper limit value setting unit is configured to change the upper limit value according to at least one predetermined condition.

The present invention is a method and system for collection of exhaust emissions installed in vehicles and disposal thereof, based on pollution conditions of the surrounding environment, said conditions identified either from sensors installed on the vehicles themselves, or by means of an external service, e.g. the Internet, cloud service, etc.

A vehicle control system and a method of operating thereof may include determining a first ratio at which to operate a vehicle system at a first location along a route along which the vehicle system moves. The first ratio may be based on an amount of a first fuel of a first fuel source relative to an amount of a second fuel of a second fuel source. The vehicle system may be powered by one or more of the first or the second fuel sources. First operational settings at which to control the vehicle system may be determined based on the first ratio between the first and second fuel sources at the first location along the route. Operation of the vehicle system may be controlled according to the first operational settings to move the vehicle system according to the first ratio at the first location along the route.

Methods and systems are provided to heat a catalyst of an after-treatment system for a vehicle. The after-treatment system is powered by a battery. An operational parameter of the battery and the driving mode of the vehicle is determined. After receiving an indication that a first operational parameter threshold has been surpassed and a torque demand of the vehicle has been predicted, heat is provided to the catalyst of the after-treatment system based on the predicted torque demand of the vehicle surpassing a second operational parameter threshold.

The invention concerns a method (200) for operating a motor vehicle (100) with a combustion engine (110), including the determination (210) of a current operating state of the vehicle (100), the determination (220) of an emission state of the vehicle (100) during the determined operating state, carrying out (230) at least one measure to reduce emissions depending on the emission state and evaluating (240) the at least one measure in connection with the operating state with regard to its success in reducing emissions. Furthermore, a computing unit (130) and a computer program product for carrying out such a method (200) are proposed.

A fuel filter monitoring method includes receiving pressure signals that are indicative of a pressure drop across at least one fuel filter of a fuel supply system configured to supply fuel to at least one fuel injector of an internal combustion engine and receiving a condition signal indicative of a condition of a fuel supply system, the condition signal being generated by one or more of a geographic location sensor, an altitude sensor, and/or a fuel temperature sensor. The method includes estimating a remaining life of at least one fuel filter of the fuel supply system based on the pressure signal and the condition signal and outputting a notification indicative of the estimated remaining life.

Methods and systems are provided for reverse purging of a fuel vapor canister of an engine. In one example, a method may include heating a fuel vapor canister, sealing a fuel tank in order to generate a vacuum in the fuel tank, and in response to the pressure in the fuel tank reaching a target vacuum, initiating reverse purging of the fuel vapor canister.

An internal combustion engine operates so that it delivers zero or negative torque. The engine operates in either a deceleration cylinder cut off (DCCO) mode or skip cylinder compression braking mode. In the skip cylinder compression braking mode, selected working cycles of selected working chambers are operated in a compression release braking mode. Accordingly, individual working chambers are sometimes not fired and sometimes operated in the compression release braking mode while the engine is operating in the skip cylinder compression braking mode.

A system comprising

a distribution grid (2) for a fuel,

combustion engines (3), which are coupled with the distribution grid (2) and are configured to combust the fuel, and

a computer system (4) comprising data connections (5) to the combustion engines (3) and a data storage device (6), wherein the computer system (4) is configured to receive engine operation parameters stemming from an operation of the combustion engines (3) at a first time and/or during a first time period via the data connections (5) and geographical data of the combustion engines (3) are stored in the data storage device (6), wherein

the computer system (4) has a processor (7) which is configured to compute a prediction for at least one characteristic parameter of the fuel at a second time and/or during a second time period later than the first time and/or the first time period and with respect to a geographical location, and

the computation of the prediction being based on the geographical data and the engine operation parameters of the combustion engines (3).

This work vehicle has: a positioning unit for measuring the current position and the current direction of the vehicle body using a satellite positioning system; and an automatic travel control unit for executing automatic travel control based on positioning information from the positioning unit. The positioning unit comprises: a plurality of positioning antennas provided on the vehicle body; a plurality of positioning units for measuring the positions of the positioning antennas; a calculation unit for calculating the current position and the current direction of the vehicle body on the basis of positioning information from the positioning units; and a positioning state determination unit for determining whether or not the positioning state of the positioning units is a high-accuracy positioning state. When at least two positioning units are in the high accuracy positioning state, the positioning state determination unit permits the start of the automatic travel control.
