A disclosed accelerator level display deviceincludes an accelerator level detection unitconfigured to detect an accelerator level; a target accelerator level determining unitconfigured to determine a target accelerator level for the accelerator level; and a display unitconfigured to display a target accelerator level indicator corresponding to the target accelerator level and an accelerator level indicator corresponding to the detected accelerator level. The display unit is configured to display the target accelerator level indicator as a fixed value regardless of the target accelerator level determined by the target accelerator level determining unit.

Accelerator level display device and accelerator level display method

A vehicular drive assist system that analyzes information collected from a vehicle and sends a result of analysis to the vehicle and/or another vehicle, including a vehicle-mounted apparatus () mounted in the vehicle, and a communication center () that communicates with the vehicle-mounted apparatus (). The vehicle-mounted apparatus () detects a present position of the host vehicle, detects a vehicular state of the host vehicle, and sends the present position and the vehicular state at the position detected to the communication center (). The communication center () performs statistic processing of the vehicular state received, separately for each predetermined area on a road, by using the present position, calculates a tendency of the vehicular state separately for each predetermined area, evaluates ease of travel on the road in the predetermined area from the tendency calculated, and sends a result of evaluation to the vehicle and/or another vehicle.

An apparatus, a method and a system of vehicle abnormality notification in which predetermined information is transmitted to a predetermined subject when an abnormality in the vehicle state is detected in a vehicle are constructed so that even when an abnormality in the vehicle state has been detected in the vehicle, the aforementioned predetermined information is not transmitted to the predetermined subject if the vehicle is in a predetermined area.

In a vehicle communication method in which communication between a plurality of communication devices is performed and an amount of communication data sent from each communication device is changed, features are as follows. That is, if the amount of communication data sent from the first communication device is to be increased, the amount of communication data sent from the second communication device is decreased so that a total sum of the amounts of communication data sent from all the communication devices does not exceed a predetermined value.

An energy-saving driving promotion system includes: a vehicle state detecting device; a current value calculating device that calculates a current value associated with an accelerator operation amount or a vehicle drive power; a recommended value calculating device that calculates a recommended value associated with the accelerator operation amount or the vehicle drive power; an indicator device that indicates a relationship between the calculated recommended value and the calculated current value; and an acceleration intention determining device that determines whether a driver intends to accelerate. If the acceleration intention determining device determines that the driver intends to accelerate, the recommended value calculating device calculates a larger recommended value when the acceleration intention determining device determines that the driver intends to accelerate than when the acceleration intention determining device determines that the driver does not intend to accelerate.

Energy-saving driving promotion system and method

A vehicle remote control apparatus for causing a vehicle to perform a requested operation in response to a remote operation request from a vehicle user includes an acquisition unit configured to acquire information about vehicle condition of the vehicle, and an operation instruction transmission controlling unit configured to compare a remote operation requested from the vehicle user with the information about the vehicle condition, to transmit an operation instruction corresponding to the requested remote operation to the vehicle if the requested remote operation has not been performed, and to refrain from transmitting an operation instruction corresponding to the requested remote operation to the vehicle if the requested remote operation has already been performed at the vehicle and is thus not performable.

Vehicle remote control apparatus and system

An engine control apparatus includes a first intake valve and a second intake valve provided along an intake passage. First and second actuators drive the respective throttle valves. A setting unit sets a vehicle target speed in the constant cruising speed control mode. A first control unit controls the first actuator so as to maintain the actual vehicle speed at the target speed during the constant cruising speed control mode. An angle sensor detects the angle of the first throttle valve. A mode memory stores information about a plurality of control modes to be used in controlling the second throttle valve. A mode selector selects one of the control modes. Each control mode stored in the mode memory defines the target angle of the second throttle valve that depends on the angle of the first throttle valve. In accordance with the control mode selected by the mode selector, a second control unit controls the second actuator in such a way that the angle of the second throttle valve becomes the target angle determined in accordance with the first throttle valve angle. The control apparatus includes a regulator unit for regulating the first and/or the second control units, so as to control the first throttle valve in accordance with the control mode specified for the constant cruising speed control mode, while the constant speed control mode is in progress.
