摘要:
A driving force control system for vehicle for controlling a target speed of an engine serving as a prime mover by selecting a control mode based on an index representing a driving preference of a driver. The control mode is selected from a first mode for operating the engine to achieve the target speed while optimizing a fuel economy, and a second mode for operating the engine to achieve the target speed at a speed lower than that achieved while optimizing the fuel economy. The driving force control system is configured to determine a lower limit speed of the engine based on the index provided that the second mode is selected, and to restrict a lower limit value of the target speed of the engine to the lower limit speed in case the target speed of the engine exceeds the lower limit speed under the second mode.

A driving force control device of a vehicle is provided which is configured to calculate a required braking force on the basis of an amount of pressure applied to a brake operating mechanism, which is operated for deceleration by a driver, and to control a braking force of a power plant, which includes a drive source generating an accelerating force and a braking force, and a braking force of a braking mechanism, which generates a braking force with the operation of the braking operating mechanism, in cooperation so that the total braking force of the vehicle as a whole becomes the required braking force. The driving force control device is configured to detect acceleration information including a lateral acceleration of the vehicle and to control the braking force of the power plant on the basis of the detected acceleration information when the brake operating mechanism is operated.

A control system for a vehicle, includes: a controller that is configured to obtain an index on the basis of a running condition of the vehicle, to vary a running characteristic of the vehicle on the basis of the index, and to vary details output from an effect producing device, which applies a stimulus to at least part of five senses of a driver of the vehicle, on the basis of the index, wherein when a variation in the running characteristic because of a variation in the index decreases, quickness of a behavior of the vehicle, the variation in the index in response to a variation in the running condition is relatively delayed, as compared with when the variation in the running characteristic because of the variation in the index increases quickness of the behavior of the vehicle.

摘要:
A vehicle control system capable of improving drivability by reflecting driving environment and driving preference accurately on driving characteristics. The vehicle control system is configured to change an index for setting driving characteristics of the vehicle. When accelerations Gx and Gy are changed, a sportiness index is changed in a different manner depending on a detail of an operation for changing accelerations Gx and Gy executed by a driver, thereby reflecting the driving preference of the driver appearing on the operation can be reflected on sportiness of the vehicle.

摘要:
A control system for an internal combustion engine comprising a direct cylinder fuel injection valve for directly injecting the fuel into a cylinder of an internal combustion engine. The main fuel that burns in the cylinder is injected in the latter half of the compression stroke of the cylinder, and the secondary fuel which is the ineffective fuel that does not burn in the cylinder is injected in the latter half of the exhaust stroke, the main fuel and the secondary fuel being injected toward a cavity formed in the top surface of the piston. The main fuel that is injected is deflected by the cavity to form a charge of a combustible air-fuel ratio mixture around the spark plug. When the secondary fuel is injected, the exhaust valve is opening, and the fuel that is deflected is all discharged out of the cylinder through the exhaust port.

An exhaust gas purification device comprising a three way catalyst, an oxidizing catalyst and a NOx absorbent which are arranged in this order in the exhaust passage. A rich air-fuel mixture is burned in the combustion chamber, and secondary air is supplied upstream of the three way catalyst so as to make the air-fuel ratio of the exhaust gas flowing into the three way catalyst a rich air-fuel ratio greater than the air-fuel ratio of the air-fuel mixture burned in the combustion chamber. Further, secondary air is supplied upstream of the oxidizing catalyst to make the air-fuel ratio of the exhaust gas flowing into the oxidizing catalyst and the NOx absorbent slightly leaner than the stoichiometric air-fuel ratio.

A first circuit has a first threshold value so set that the first output signal is judged to be a predetermined logical value in response to the first binary signal and to be a logical value corresponding to a logical value of the second binary signal in response to the second binary signal. A second circuit has a different threshold value so set that the second output signal is judged to be a predetermined logical value in response to the second binary signal and to be a logical value corresponding to a logical value of the first binary signal in response to the first binary signal.
