Provided is a technology that, when an unmanned haulage vehicle and a manned haulage vehicle are allowed to exist together and are subjected to fleet operations management, can provide driving assistance to an operator of the manned vehicle by using control data similar to those to be transmitted to the unmanned haulage vehicle. To this end, the manned vehicle is provided with a terminal-side communication control unit, a control command value conversion unit and a control command value providing unit. The terminal-side communication control unit receives, from a fleet operations management server that performs operations management of the unmanned haulage vehicle, a control command value for allowing the unmanned haulage vehicle to travel autonomously. The control command value conversion unit converts contents of the control command value to perceivable information. The control command value providing unit provides the perceivable information to the operator.

The present invention can realize a vehicle running control apparatus including ACC function and map information data recording medium to obtain effective information for safety driving capable for running control meeting a driver's feeling. The first running speed is decided on the basis of the distance between the vehicles and the relative speed. The position detecting means detects the position of own vehicle on a map. The map information getting means gets road information, the width of the road, the radius of curvature, and slope on the basis of the map information. The visible distance estimating means estimates the visible distance on the basis of the map information, deciding the second running safety speed with the estimated visible distance. The running control means decides the object running speed of smallest one of the set speed, the first running speed, and the second running speed.

When a throttle is fully open, a maximum torque set value is corrected based on the ratio between the maximum air volume set value under fully-open throttle conditions and the actual maximum air volume detected by an intake air volume meter such as an air flow sensor. Based on the corrected maximum torque set value, both the relation between the degree of accelerator opening and target torque and the relation between the target torque (target air volume) and the degree target throttle opening are corrected. Thus, even when various types of disturbances relating to torque error are generated, such as variations in air density generated in association with variations in temperature or altitude, variations over time such as contaminations of throttle chambers, or difference between machines such as engine bodies or auxiliary machines, it is possible to generate actual torque with respect to a target torque with a high degree of accuracy, while maintaining a desired relation between the degree of accelerator opening and the throttle opening.

Engine controller and controlling method

In order to estimate failure times of vehicles, the invention provides a vehicle failure diagnosis apparatus which receives records of learned values actually used in the past in vehicle control systems of vehicles as diagnosis targets from in-vehicle terminals via a communication part, estimates failure time of the vehicle control systems by comparing the received records of the learned values and the failure patterns readout from a failure pattern DB, and outputs the estimated failure time to the in-vehicle terminals.

A large gearshift shock that occurs if a renewed gearshift operation is forcibly carried out in order to meet a new gearshift request made through a driver's operating an accelerator pedal or a signal from an operation lever during a current gearshift operation. Gearshift response lag occurs due to an attempt to avoid the large gearshift shock. To solve these problems, a control system for a gear type transmission is mounted. The control system is provided with a renewed gearshift disabling period, during which any renewed gearshift request to a third predetermined gearshift position made during a gearshift operation from a first predetermined gearshift position to a second predetermined gearshift position is disabled.

An apparatus and a method for controlling an automotive vehicle are disclosed, in which a control amount for securing safety of the vehicle and the control amount for achieving a state intended for by the driver of the vehicle are switched in such a manner as to reduce the shock due to the change in the torque generated from the power train, thereby accomplishing both safety and maneuverability at the same time. A first target value is set for controlling at least selected one of the driving torque, the driving force and the acceleration/deceleration rate. A second target value is calculated in accordance with the drive mode intended for by the driver or the driving environment ahead of the vehicle. In the case where a deviation exceeding a predetermined value develops between the first target value and the second target value, the fluctuations of at least one of the driving torque, the driving force and the acceleration/deceleration rate are suppressed.
