A rough road determination device (100) is mounted on a vehicle (1) that is equipped with an internal combustion engine (10) having a crank angle sensor (31). This rough road determination device is equipped with determination means (20) for determining whether or not a road on which the vehicle travels is a rough road, by comparing a first amplitude fluctuation amount as an amplitude fluctuation amount of one pulse of an output of the crank angle sensor, which is determined in advance on the basis of a rotational speed of the internal combustion engine, with a second amplitude fluctuation amount as an amplitude fluctuation amount of one pulse that is actually output from the crank angle sensor.

A device for predicting energy consumption includes an obtaining unit (110), an air resistance calculating unit (140, 150), and an energy consumption predicting unit (150). The obtaining unit (110) is configured to obtain road information including traveling speed information set for each route. The air resistance calculating unit (140, 150) is configured to calculate air resistance as a calculated air resistance value by an air resistance calculation formula on the basis of the traveling speed information of the scheduled traveling route and to correct the calculated air resistance value so that the air resistance is higher according as the traveling speed along the scheduled traveling route is lower. The air resistance is caused when a vehicle travels along a scheduled traveling route. The energy consumption predicting unit (150) is configured to predict an energy consumption of the scheduled traveling route on the basis of the corrected air resistance value.

摘要:
A method of introducing additives to an air intake system of an engine in order to overcome one or more of the various problems created by formulation of additives in fuels. The method controls at least one of the amount, aerosol particle size and timing of introduction of additives based on information relevant to operation of the engine. The introduced additives form an air-additive mixture and are carried by the airflow in the air-intake system to the combustion chamber of the engine. Another aspect of the invention is an additive introduction system that includes one or more containers for additives, a control system for determining at least one of the amount, aerosol particle size and timing of introduction of the additives, and a device to introduce the additives into the air intake system under the control of the control system.

摘要:
The present invention relates to a motor vehicle with a clutch (3) and an automated transmission (9) between the engine and the drive wheels of the vehicle. The vehicle has a first electronic control unit (48) for controlling the engine, a second electronic control unit (45) for controlling the transmission, depending on a set position of a manual gear selector (46). The second control unit, with the gear selector in position for automatic shifting, selects a gear for starting off or under way, which is determined by the gear selection strategy stored in the second control unit as a function of various parameters fed into the second control unit. The invention is characterized in that the second control unit is disposed, at starting off or under way, to continuously perform computer simulations, at least on the basis of information on road incline and throttle opening position, of the future travel of the vehicle, for a set of different combinations of shift rpm:s and shift increments. This is in accordance with a criterion selected automatically or manually by the driver, using a switch. The second control unit selects out a shifting schedule which will be optimal in accordance with the selected criterion.
