- step S13 it is determined in the driving support determination unit 37 whether or not it is the emergency intervention control area A23 (step S13). If it is determined that it is the emergency intervention control area A23, the driving assistance control unit 39 calculates a control amount for emergency avoidance (step S14). On the other hand, if the emergency intervention control area A23 is not determined, the process proceeds to step S15.
- step S15 driving support is implemented. Specifically, a warning is given to the driver by the HMI 9. In addition, intervention control is performed by the intervention control ECU 11 together with a warning by the HMI 9.
- step S16 the virtual moving speed (virtual speed) of the moving body is set by the collision time prediction unit 33. Then, based on the virtual moving speed of the moving body, the virtual TTC and the virtual TTV are calculated by the collision time prediction unit 33 (step S17). Then, the virtual TTC and the virtual TTV calculated by the collision time prediction unit 33 are applied to the map M2 stored in the map storage unit 35 (step S18), and it is determined whether or not driving assistance is to be performed in the host vehicle. This is performed in the driving support determination unit 37.
- the driving support determination unit 37 determines whether or not the intersection of the virtual TTC and the virtual TTV is the HMI area A41, that is, the driving support area A4 (step S19). If it is determined that the area is the HMI area A41, the HMI operation flag is set to “1” (step S20). On the other hand, when it is not determined that the area is the HMI area A41, that is, when it is determined that the area is the driving support unnecessary area A3, the process returns to the step S01.
- step S21 it is determined in the driving support determination part 37 whether it is intervention control area A42 (step S21). If it is determined that it is the intervention control area A42, the driving support control unit 39 calculates the control amount of the intervention control based on, for example, the map M2 (step S22). On the other hand, if it is not determined that it is the intervention control area A42, the process proceeds to step S15.
- step S23 it is determined in the driving support determination part 37 whether it is emergency intervention control area A43 (step S23).
- the driving assistance control unit 39 calculates a control amount for emergency avoidance (step S24).
- step S24 the process proceeds to step S15.
- the intersection point CP where the host vehicle and the moving body intersect is predicted, the virtual TTC until the host vehicle reaches the intersection point, and the virtually set virtual speed vp.
- the virtual TTV until the moving body reaches the intersection CP is obtained.
- driving assistance can be implemented by predicting the crossing of the moving body, driving assistance can also be implemented for a moving body that has not actually crossed. Accordingly, it is possible to cope with a case where the moving body suddenly changes its direction in the transverse direction when passing the side of the moving body. Therefore, the reliability can be improved.
- the angle A formed by the predicted movement direction of the host vehicle and the direction of the moving body is calculated. If the formed angle A is equal to or greater than the threshold value B, whether or not driving assistance is performed using the map M1. If the angle A formed is smaller than the threshold value B, it is determined whether or not driving assistance is to be performed using the map M2. In this way, by changing the maps M1 and M2 used according to the formed angle A, it is possible to implement driving support optimal for the positional relationship between the host vehicle and the moving body.
- the maps M1 and M2 include driving support unnecessary areas A1 and A3 and driving support areas A2 and A4.
- the driving support areas A2 and A4 include HMI areas A21 and A41 and an intervention control area A22. , A42 and emergency intervention control areas A23, A43 are set.
- the present invention is not limited to the above embodiment.
- the map M1 and the map 2 are used separately, but the map M1 and the map M2 may be one map.
- the warning by the HIM 9 is also performed at the same time.
- the warning by the HIM 9 may not be performed.
