What are the collision avoidance specs?

    If anyone has them handy. My old man memory thinks it is a maximum in the mid 30s mph.

    Thanks,

    Hummm, thanks but I was looking for the threshold speed to not hit the pedestrian. This reads more like detection and not avoid impact. Did I get it wrong?

    The screenshot from the manual was from the PCS section, below I pasted the general description, so I think this is it.
    PCS (Pre-Collision System)
    [​IMG]
    The pre-collision system uses a radar sensor and camera sen- sor to detect vehicles and pedestrians in front of your vehicle. When the system determines that the possibility of a frontal col- lision with a vehicle or pedestrian is high, a warning operates to urge the driver to take evasive action and the potential brake pressure is increased to help the driver avoid the collision. If the system determines that the possibility of a frontal collision with a vehicle or pedestrian is extremely high, the brakes are auto- matically applied to help avoid the collision or help reduce the impact of the collision.

    This source suggests that if you're going faster than 20-50 mph, it won't be able to stop you in time to completely avoid collision. But that's quite a range and it's not clear what the basis for it is - maybe they taking into account weather, road conditions, etc.?

    Whatever the IIHS test limit is (seriously).


    I think it's.... 19mph (30km/h) pedestrian, 25mph (40km/h) vehicle? (for the best chance of coming to a stop before colliding with the object)

    Would need to know the detection range to know if you could stop at a given speed. Do we know what system Toyota is using? Mobileye? Looks like Toyota is in house for this system.
