The invention provides a vehicle braking intention grade determination method, electronic equipment and a storage medium, and belongs to the technical field of vehicle braking control. The control method comprises the steps that a displacement signal reflecting the motion state of a brake pedal is obtained; based on the displacement signal, the movement speed and the movement acceleration of a brake pedal are determined; according to the displacement signal, the movement speed and the movement acceleration, a braking intention intensity quantized value is generated through a preset fusion rule; the braking intention intensity quantized value is compared with a plurality of preset grade threshold values, and the current target braking intention grade is determined; and outputting the target braking intention level to a vehicle control system for vehicle control. The target braking intention level is determined by fusing the pedal displacement, the speed and the acceleration, early, accurate and reliable recognition of the braking intention level is achieved, and therefore the real braking intention intensity of a driver can be accurately distinguished.

This invention belongs to the field of molecular biology technology for chili pepper breeding, and discloses a molecular marker, primers, and their applications related to capsaicin content. The molecular marker uses the “zhangshugang” version of the genome as a reference gene, and its flanking nucleotide sequence is shown in SEQ ID NO: 1. The primers are shown in SEQ ID NO: 2-4. This invention also provides the primers or kits for identifying and assisting in the screening of chili pepper spiciness, or for the identification, screening, or breeding of non-spicy chili pepper fruits. This invention achieves early, accurate, and high-throughput identification of the “non-spicy” and “spicy” traits in chili peppers. The developed KASP molecular marker can complete genotyping within hours using only a small amount of leaf DNA during the seedling stage, accurately predicting the spiciness phenotype of mature fruits, moving the selection process from the field to the laboratory, and breaking through the spatial and temporal limitations of phenotypic identification.
