By using SAE 95% human body arrangement, combining developed vehicle type arrangement experience and subjective evaluation results on a human-machine table, and through a large number of competitive bidding analysis, the height of the rear sitting position of the family car is recommended to be more than 290mm, the height of the rear sitting position of the business type car is more than 300mm, otherwise, the hip angle of the rear passenger is small, and the riding comfort is poor.
S402, effective head space height range H61-2
The head space is an important parameter for a client to evaluate whether the internal space of the whole vehicle is good or not, the riding comfort of passengers in the back row can be improved by the larger head space, the defect of increase of the height of the whole vehicle can be brought, the modeling proportion is influenced, the endurance mileage of a part of electric vehicles can be sacrificed, the vehicle height and the head space need to be considered in a balanced manner, and the invalid vehicle height is not increased too much on the premise of meeting the requirement of the head space.
The height of the effective head space is from a reference point of a rear-row seat, and is in a direction of forming an 8-degree angle backwards along the vertical direction of the effective head space, and the distance from the reference point of the seat to a ceiling above the head of a rear-row passenger is added with 102 mm;
the effect is evaluated by selecting an SAE 95% human body combination model, the effective head space H61-2 is more than or equal to 935mm, which is a comfortable space state, if the lower vehicle height is to be realized, the effective head space H61-2 can be considered to be properly sacrificed and is not less than 925mm, the preferred range is 925-960mm, and the range is not limited to the range. It should be understood that the greater the head space, the greater the comfort theoretically, but the higher the vehicle height. The vehicle height can be realized from the engineering feasibility only by being larger than the vehicle height, and the specific vehicle height depends on the shape of the vehicle on the premise of feasibility.
S403, taking the sum of the height range of the rear sitting position and the height range of the effective head space in the steps as the Z-direction height range of the rear passenger compartment, namely the Z-direction height range of the rear passenger compartment of the family car is [1215mm, 1340mm ]; the Z-direction height range of the passenger compartment at the back row of the commercial car is 1225mm and 1360 mm.
6. Ceiling height range at top of rear row
If the top decoration type is a skylight-free type, and the skylight is only positioned above a driver or an outward opening type panoramic skylight, the height of the ceiling at the top of the rear row head is a first set height range, and the first set height range is preferably [25mm, 35mm ], but not limited to the range; if the top decoration type is a transparent hard top cover, the ceiling height at the top of the rear row head is a second set height, and the second set height is preferably in a range of [4mm, 6mm ], but not limited to the range.
And S3, summing the height range of the power battery from the ground, the thickness range of the power battery, the Z-direction distance range from the upper surface of the power battery to the heel point of the passenger, the height range of the Z-direction space of the passenger compartment in the rear row, the height range of the ceiling at the top of the head in the rear row and the reserved height range of the modeling space to obtain the range of the lowest vehicle height of the whole vehicle.
The range summation is to sum the minimum value of each range to be the minimum value of the range of the lowest vehicle height of the whole vehicle, and sum the maximum value of each range to be the maximum value of the range of the lowest vehicle height of the whole vehicle;
according to the boundary definition of the project on the vehicle height, the vehicle height of the whole vehicle is calculated by the vehicle type modularization rapid vehicle height setting method according to the vehicle type configuration, and if the vehicle height required by the project is higher than the minimum vehicle height which can be realized, the project requirement is met; if the vehicle height required by the project is lower than the lowest vehicle height capable of being realized, the vehicle height required by the project cannot be achieved, and the target needs to be adjusted.
