摘要:
Improved is determination accuracy on whether or not a driver is erroneously performing an accelerator operation instead of a brake operation. A pedal opening degree PPO by a driver and a continuation time Te for which the pedal opening degree PPO is greater than an opening degree threshold value Pth are detected. When the continuation time Te exceeds a time threshold value Tth, it is determined that the driver is erroneously performing an accelerator operation instead of a brake operation. A vehicle speed V of a vehicle, a rising gradient Sr of a road surface, and an accelerator operation time Tp operated by the driver are detected. The opening degree threshold value Pth is made variable in accordance with the vehicle speed V, the rising gradient Sr, and the operation time Tp. The time threshold value Tth is made variable in accordance with the vehicle speed V, the rising gradient Sr, and the operation time Tp.

To achieve an earlier start time for starting driving assist control, while ensuring a function for preventing erroneous determination of a pedestrian during travel. External environment recognition sensors that acquire forward information of a host vehicle (A) are provided, and an automatic brake control for avoiding contact between the host vehicle (A) and a pedestrian (B) is executed, when a pedestrian B is detected by the external environment recognition sensors. In this driving assist control method for an electrically driven vehicle, a front camera unit (1) and a millimeter wave radar (2) are provided as the external environment recognition sensors. When an object that is present in front of the host vehicle (A) is detected to be a pedestrian candidate (B') based on an image signal from the front camera unit (1), execution of an automatic brake control is permitted, with the detected pedestrian candidate (B') as the control target. Thereafter, it is determined using comparison whether or not the pedestrian candidate (B') detected by the front camera unit (1) matches an object (D1) detected by the reflected waves from the millimeter wave radar (2), and it is determined whether or not to continue execution of the automatic brake control based on the result of the comparison determination.

A vehicle acceleration suppression device includes an obstacle relative distance detector (32) configured to detect a relative distance between a vehicle and an obstacle, a drive force manipulation amount detector (34) configured to detect a drive force manipulation amount that is a manipulation amount of an accelerator pedal (30), a steering manipulation amount detector (36) configured to detect a steering manipulation amount that is the manipulation amount of the steering manipulation element, and a drive force limit unit (44) configured to limit the drive force of the vehicle to a predefined drive force limit value, depending on the steering manipulation amount detected by the steering manipulation amount detector (36), when the relative distance detected by the obstacle relative distance detector (32) is equal to or shorter than a predefined limiting relative distance and the drive force manipulation amount detected by the drive force manipulation amount detector (34) exceeds a predefined drive force manipulation amount threshold.
摘要:
A total certainty factor indicating a total degree of certainty of the parking frame certainty degree and the parking frame entering certainty degree is calculated based on a parking frame certainty degree indicating the degree of certainty that a parking frame is present in a travel direction of a vehicle, and a parking frame entering certainty degree indicating the degree of certainty that the vehicle enters the parking frame. When the total certainty factor is low, acceleration of the vehicle controlled according to an operation amount of an accelerator pedal for instructing a driving force by operation of a driver is suppressed with a low suppression degree, as compared with a case where the total certainty factor is high. Further, the acceleration of the vehicle is suppressed with a lower suppression degree as the vehicle speed of the vehicle is higher.
摘要:
To improve pedestrian determination responsiveness, when determining a pedestrian using a camera and a radar during travel. External environment recognition sensors that acquire forward information for a host vehicle (A) are provided, to determine that a pedestrian (B) is present in a forward position of the host vehicle (A) using the external environment recognition sensors. In this pedestrian determination method, a front camera unit (1) and a millimeter wave radar (2) are provided as the external environment recognition sensors. When a pedestrian candidate (B') is detected in a forward position of the host vehicle (A) based on an image signal from the front camera unit (1), a matching area (C) is set with the position of the detected pedestrian candidate (B') as the center point. When the position of the object (D1) that is closest to the pedestrian candidate (B') from among the plurality of objects (D1, D2, D3) detected by reflected waves from the millimeter wave radar (2) is within the matching area (C) thereby establishing a match, the pedestrian candidate (B') is determined to be a pedestrian (B).
摘要:
In the case that a vehicle 1 is making a reverse movement, a control section 4 sets a braking control operation distance according to an angle formed by the vehicle 1's proceeding direction and an extending direction of a road on which an approaching vehicle is traveling. With this, a braking control is implemented at a delayed timing in a scene where the following possibility is high: the driver wishes to end the reverse movement operation as early as possible when a space for allowing the approaching vehicle to pass by is not present at the back of the vehicle 1. Thereby, the cumbersomeness or discomfort which may be felt by the driver with respect to the braking control can be decreased.
